Ask HN: How do I protect my parents from the internet?

236 points by throwawaywxc ↗ HN
I recently came home to find the home PC has been bricked - the boot layer has somehow been corrupted.

This is pretty remarkable given that my dad only uses it watch golf videos and edit some photos in lightroom. He may occasionally indulge in some porn cough.

I figured he'd be relatively safe as I installed an Adblocker and had Norton installed on the device but I did not realise how vulnerable he was until I found out he can't tell the difference between a pop up and a genuine desktop notification. He has even clicked through on a "You have been chosen to win an iPhone 7" link recently - he saw no harm in at least seeing what might happen.

He also likes to download videos from youtube so I taught him how to use youtube-dl but ended up downloading some malware-infected ripper because it had a more convenient UI.

How do I educate someone from such a base level?

What can I put on the PC to protect them? I avoided using scriptblockers as I don't think they are tech savvy enough to work out why a page might not be working.

Install them Ubuntu, KDE Neon or Mint. Works for my parents since... I dropped Windows XP.
Idem for me. I have installed Ubuntu-gnome. sshd, wine and powerpoint viewer are the main customization. When the computer is started, I receive a SMS so that I can perform updates or backups.
I did similar. PC has static IP in LAN, there is raspberry pi with duckdns and ssh waiting for me. I just login on rpi, then ssh to parents PC and do what I need. I can do updates, remove files, monitor activity and all other things, easily, for free. It's Ubuntu, they don't have sudo/root password so can't break anything, ever.

You can start with ubuntu that is immune to most of malware and enough if your parents needs are internet + video palying and downloading + office suite
Not the answer you want but an ipad might limit the damage that can be done. It would remove the need for education.
Is it still true? I would have thought that by gaining popularity Apple devices would become the target of malwares as well.
It's not that easy to break into the walled garden. There are fundamental differences between a iPad and a PC (or a Mac, if the distinction still makes sense).
(comment deleted)
Thanks for the reply! This is not at all a bad suggestion - my mum is on an iPad and actually since this happened, I realised that actually she is nowhere near as big a vector as my dad despite the fact that she doesn't know what an app is nor what a browser is.

My dad is more dangerous because he has some some idea of what he has just enough of an idea to know what he is doing but not enough of an idea to actually protect himself. He also despises all Apple products alas...

If simply educating them on what not to do (clicking on 'free' stuff, downloading without discretion) won't work, I'd suggest switching out the OS to something a little less targetted by malware. I recently got my mom a chromebook, which she loves. You say your dad uses lightroom though, so that might not work for your use case.
This is a very important conversation for this decade. Do post your solution on HN once you have it.
I was really hoping for a discussion on how to keep parents from watching videos about the healing properties of crystals and government chemtrail conspiracies...

...but to answer your question perhaps you can get your parents a Chromebook? I'm not sure what photo editing options exist on the platform, but hopefully it's an obscure enough platform to avoid the majority of malware.

Why would people lie on the internet? - my mom
Related. Conspiracy theory websites are also very dangerous places to browse. My grandfather loves conspiracy theories, mostly the ones related to free energy machines, and he told me some sites that he went to. I was curious so I visited a few of them (using Firefox + AdBlock). This was the first time I actually got a virus just by browsing a site. It used an exploit that bypassed the browser download popup security mechanism, and it just installed itself. I legitimately got owned, and I was pissed because that just does not happen to me. Now I understand why my grandfather's computer is unusable nowadays.
I hope you reported the vulnerability to Mozilla.
Use Deepfreeze or something similar. You'll mark a their documents directory as excluded and then every time they restart their machine it'll be back to the exact state it was in when you first set it up.

You don't want to have to support them using a new OS for the first time - you'll be in for a headache. I use Deepfreeze for anyone who is a "problem user" and most don't even realize they have it if it's set up right.

This is the answer.
Yeah, I didn't even know this existed!

I still think that the second-best answer is to get a tablet or phablet. My grandmother has mostly switched to an iPad and the vast majority of real problems disappeared. There's the occasional 'how I do get photo <x> to target <y>', but nothing serious.

Feels a bit like defeat though.

It's been around a long time- I'm 30 and my friends and I spent time trying to figure out ways around it in high school. (My little brother and his friends eventually did- they acquired the admin password).
What does it cost? The faronics website seems to avoid minor details like pricing.
$45, I believe there are alternatives I just don't really know anything about them.

You're right about their site though, every single time they've changed it the site has looked more scammy/crappy and been harder to get where I need to go. If I hadn't used their product before I would go to that site and immediately leave.

We run Deepfreeze in our library and its cut out all of the problems we were having. Very solid product, but a little spendy. We will probably deploy it a bit more widely when we go to Windows 10.
Maybe I'm being dumb, but couldn't you just lock down the level of user access on the machine?

As another option, assuming you can use Linux, could go down the route of using Tails or another live distro:

https://tails.boum.org/

Your not being dumb, but....

Locking down the machines is fine if you don't get any privilege exploits that take over the machine. Plus, this puts the machine in a known, good state every time we reboot or have a new user.

Cannot use Linux (I would use PC-BSD given our BSD infrastructure).

>Locking down the machines is fine if you don't get any privilege exploits that take over the machine

but in that case deepfreeze isn't going to save you either.

privilege exploits = SYSTEM access = kernel mode access = ability to bypass deep freeze (by circumventing their IO driver)

So far it has been one layer too far. plus I don't have to worry about any saves to the HD.
You could limit his user rights, make him a Standard user and don't let him install new software.

Also, have a look at how suitable a Chromebook will be for his workflow (simpler to maintain from your perspective and harder to infect).

Linux machine, subscribe to more adblocker malware prevention lists - my mother's laptop has more ticks on the adblock subscription lists than squares - and in case of my father an awkward conversation where I told him a list of safe porn sites.
This sounds very useful - do you mind giving some more flavour? What exactly did you implement?
In this respect, the FTC has failed 100% in their mission. Normal, non-tech consumers cannot use the Internet without falling prey to the outlaw landscape that is the WWW.

I think you need to explain to them that the Internet is too much like the Wild West, and they need to stick to trusted web sites, as their "sight" is not tuned to see the dangers. Leaving them too scared to randomly surf might not be a bad thing, in this situation. I have the same type of situation with my 85 year old mother. She is somewhat tech savvy, but not enough. Her browser has every possible 3rd party toolbar, no matter how much I educate her on the situation...

In addition to the stuff you mentioned, for my mother in law I:

removed her user's admin privileges

install flashblock - one of the ones where you have to click on the video to make it run

spent a long time explaining that you will never be chosen to win something, MS support never rings you to tell you have a virus, if something takes over the whole screen and tells you anything suspicious/implausible to press alt+f4

convinced her free music isnt worth the risk of downloading something that trashes the machine. installed spotify

If you are stuck on Windows or Mac you can try a program that restores the computer to a safe state on reboot, like Deep Freeze.
Not a bad idea.

What are your thoughts on file-syncing using DropBox? Solutions have to be easier than breathing - I used to take a regular image of the PC for backup purposes but then my dad would complain he couldn't actually view the files.

There are already good solutions below. The one thing I would add is that this may not be a "silver bullet" kind of problem. I'd throw everything I can into the mix to create layers of protection. Educate them but also add software solutions to the mix.

A small addition, how often do they need to install new software after initial setup? Maybe take away admin privileges?

Should hardly ever need to - but I am rarely at home so would prefer not to be in a position where any time they need to do something I need to be present.

The only real software he would need at the moment is for photoediting

How about a Chromebook?

Cheap, keeps itself up to date, fully cloud based.

It wouldn't tick the Lightroom box but it does the internet based stuff extremely well with low maintenance.

I do this for my family these days, virtually zero maintainance.

Biggest word of warning though is that Google are totally happy to change things with no warning or how or why, which can be very confusing.

For example, they stopped a direct route to import photos from an SD card or alike to google photos. No automated replacement workflow.

That's the biggest concern: being able to use the interface the way you have for ages without having to RE-familiarize yourself. This seems to be a harder hurdle for non-technical older folks. The gmail app interface changing every so often on android tablet would cause parents so much confusion that I finally replaced the tablet with a linux laptop with thunderbird
I got my mom a Chromebook. It's the most successful computing experience so far, but I was quite surprised by a few things.

She didn't realize that the password to log in to your computer was the sync'd to her Google password. So she would type some random password 5 times, until the Chromebook said "use your Google password to reset your Chromebook password", and would then log in with that. Every single time.

Some website managed to convince her to switch to developer mode to install a non-web-store extension that overwrites the new tab page and search functionality with ads. Chrome is a little more aggressive about not letting you change the New Tab page these days, asking you occasionally if you still want the extension to control it (even for the new tab page I use, an extension from Google).

But despite that, she got a lot out of the computer, so overall it worked quite well. And we fixed those two issues, so I don't think there are any problems now.

> Some website managed to convince her to switch to developer mode to install a non-web-store extension that overwrites the new tab page and search functionality with ads

I'm not even mad, I'm honestly impressed both that your mom went to such lengths and that a website managed to convince a layperson to do such a thing.

(comment deleted)
Is it really harder to change the new tab page in Chrome OS anymore? Wow.
I wanted a completely blank, empty new tab page, nothing on it whatsoever.

I had to create my own "extension" and load it up in developer mode to get the exact functionality I wanted (an empty page).

Wow, that is some seriously impressive social engineering...lol. And some determination from your mother =).

I assume this wasn't a device where she had to open the case and short out some jumpers to enable Developer Mode? =)

I literally bought my wife's parents a Chromebook yesterday. Their really old computer finally bit the dust, and when I asked them what they did on the computer it was all very simple stuff around the internet. Maps, web, email, and pictures.

Lightroom to me means the user is in the more advanced category. I'm routinely amazed at what Google photos does without any input (tagging, grouping, enhancing), and if I want to tweak pics Snapseed works really well. The only time I startup LR now is if I pull the DSLR out.

I specifically wrote my book, Digital Survival Guide, to help address this knowledge gap in digital security and safety that our society has. However, education may not be enough for everyone and you may need to take a sandbox approach. Have them use a VM and expect to refresh it from a snapshot often. Check out my book, you and your parents will find many useful tips.

No ebook version? In current year? Are you even serious right now?
In my experience, don't. Offer them your best solution for a novice user, which for me is usually an up-to-date machine with an ad blocker, and make sure that you're open for

Ultimately, they're adults, and the last thing your father will want is to be treated like a child on his own machine. If he fucks something up, fix it, and tell him what he can do to not have that issue come up again.

This is good advice in principle but my parents are from a different world they grew up in a world without fridges, TVs or electronics.

I am all for them learning and making their own mistakes but I know them well enough to know that this wouldn't really work in their case - I know them well enough that ultimately they want something that just works with minimal effort, the stakes are also high in that I don't want them bricking a PC (100s of $) or getting hit by identity fraud.

I'd go mac if my dad didn't hate it so much.

After my mom got scammed online, I had "the talk" with my parents and we agreed that they would just use iPads and iPhones.

I've had no tech support calls for a couple of years now.

I think a chromebook is a good option if a keyboard is required.

It's a losing battle at this point. Your time is better spent educating them against social engineering attacks (I'm still afraid my mom is going to return a call to the voicemail the "IRS" left)

> It's a losing battle at this point. Your time is better spent educating them against social engineering attacks (I'm still afraid my mom is going to return a call to the voicemail the "IRS" left)

The "This is Microsoft calling..." scams are even worse. Many older people have very little understanding of what is actually installed on their computer and what the various pieces do. My mother in law has fallen for the fake AV popup advert multiple times this year.

To go into detail, you'll get a call from "Microsoft", generally with a foreign accent, and they'll have you sit at your computer, screen share, and give them root access. Then they'll do some powershell command that makes scary messages flash on the screen and have you buy whatever plan in order for them to "clean" it. Usually a couple hundred bucks.

My deeper fear is that they rooted my dad's machine and have been up to nefarious stuff ever since, but i'll never know. He won't let me touch it.

Oh and the IRS is now contracting private debt collectors, so there may now be "legitimate" calls regarding the IRS....

I am the opposite of most comments here. Don't stupid her away to a mobile device.

We got our mom a computer, a cheap one, and told her to play with it. Break it. Click everywhere.

Soon enough she was playing with windows settings. Soon enough nothing worked. She now knew you can brick computer, she is more careful.

We fixed the computer and she explored the internet. She asked how she could download wallpapers, we introduced her to torrents and file sharing. She got viruses. She learned that you can get virus online and they will delete your hard worked wallpaper collection. She is aware of the dangers of the internet now.

For a while you would download all the free adblockers, anti-virus, etc., she could find and put them on CDs. She learned to clean her own computer.

Right now she is very comfortable with computers and it allows her to have more freedom. She will easily connect with people online, like we do here. I'm certain it has helped her keeping smart.

She even feel out pain now. Whenever one of her neighbours lady has issues with computers they call her.

It is after all how the rest of us learned. Windows 95 (alpha) was so unreliable you had to reinstall it monthly as it ripped itself apart so you got to know how to reinstall windows and get it setup again. I spent time in the control panel after that because I knew how to start over.

20 years later after countless errors my computer gets reinstalled when Microsoft pushes out a garbage patch or I get new hardware.

> It is after all how the rest of us learned.

Thank you for this very important reminder. Everyone has to learn this at some point, and will necessarily start from a position of relative ignorance; the fact that someone hasn't learned it yet doesn't mean that he or she is stupid, and it's wrong to treat it as such. (Not to say that anyone here, particularly the poster, has said or even thinks this; but it's easy to fall into that mindset, at least for me.)

I like this approach. But how did you mitigate the risk of a more serious data compromise like identity theft? Did you wait until she understood the dangers before allowing her to use sensitive logins like banking and email?
Online transactions weren't as safe and ubiquitous back then. She already had a paranoia of entering those informations online and we told her that her instinct was right.

She does some Amazon orders every now and then but that's it.

Good question and good answer through your rhetorical question too. GP approach with your addendum is the way to do this in my opinion.
This assumes an interest, willingness, and time to learn. For better or worse, not everyone can/wants to become an expert in managing these buggy and vulnerable messes we call general purpose computers.

It's a big investment, an investment many of us don't remember making since it was effectively part of our childhood. That same investment, in a world with special purpose computing devices, has a very low ROI for people who would rather be doing something else.

It's also assuming you live close enough to your parents that you can go over and physically revive a bricked computer.
There's got to be money in a service where a company provides your parents with a computer that's set up to be pretty user friendly and safe. If they brick it, the computer is replaced. The company manages the machine so backups are handled and the new machine will be pretty close to whatever they lost wherever possible (in terms of content on the machine). If the hardware gets damaged that'd have to be paid for I guess.
Yeah, Google provides that service and many manufacturers sell the products which make use of it. (chromebooks)
I just thought of a bizarre but interesting idea - an i3/i5-capable server motherboard with IPMI, and a rock-solid router running OpenVPN in front of the IPMI port.

Maybe fractionally higher power consumption, and perhaps you'd need a GPU for it, but if both ends have really decent internet, that could very legitimately work.

> a rock-solid router

Make one of these and you'll end up with a lot of money.

Where would be a good place to start? OpenBSD? http://www.skeptech.org/blog/2013/01/13/unscrewed-a-story-ab... Another platform?

It's tricky. You could for example pick seL4, but then you have no router. That could be interpreted as an amazing opportunity to make a new stack, or a feat significantly less interesting and more strenuous than climbing Mt. Everest.

Then on the hardware side, do you pick x86 (complete with firmware that lets you use fallthru to ring -2! \o/), ARM, MIPS, or what? This is a question I've no idea how to answer.

Also, heh, I'm reminded of this:

1. Search Shodan for JAWS/1.0

2. Take one of the results, go to the IP[:port], append "/shell?" and a command, eg "/shell?ls"

3. Try running "whoami"

4. Go back and look at the number of results

5. Visit the IPs normally, and learn that these are DVRs, for security cameras; alternate between dying inside and reattaching your jaw.

> She asked how she could download wallpapers, we introduced her to torrents and file sharing

But... why?

Ever been to those "super-awesome-hd-wallaper.com" websites? They are FILLED with ads, popups, etc.

Instead, you can safely download one of the top wallpaper torrent package on Pirate Bay and get thousands of good quality wallpapers.

Or ya know... Google Images...
Is it that hard for you to accept that people use different tools to accomplish the same task?
It's a little bizarre to introduce someone to torrents when you can use google images. Especially someone who is struggling to grasp computing as a whole.
Psst... Didn't want to focus the discussion on the legality of torrenting. Of course she uses torrent for more than only wallpapers. ;)
I find it a bit ironic that 4chan's /wg/ of all places seems like the safest choice here. Plus, the content is always up-to-date
wallbase.cc used to be an archive that scraped the various wallpaper boards on the chans, it worked brilliantly with colour searching, tagging and they had a fantastic supply of dual/triple monitor papers.
now that looks like something that can be a nice side-project. Thanks for the great idea!
There's alpha.wallhaven.cc now but it's nowhere as good as wallbase used to be.
Teaching someone to fish only works when they want to learn. For the vast majority of people who just want to consume the media available on the net, this would be a monumental waste of time.

It's like me trying to fix my own car just for the sake of knowing how to fix my own car. Nope. No thanks. I'll take it to the garage when it's broken.

For most people I would recommend an iPad or a smartphone.

That's pretty much how we all learned. Good on your mom!
tldr: Linux.

I had more or less the same issue (except things still booted) with my parents about 5 or 6 years ago. In a move I thought was insane, I put them on Xubuntu. I moved them to Mint for a while, but they are back to Xubuntu. It's my preferred distro, and the Ubuntu base (for good support) and XFCE (Windows familiarity) made me comfortable it was Mom and Dad proof. Aside from showing them where things are, there have been zero problems. Turns out that Linux is just as good for email, web browsing, Youtube, and solitare.

I haven't used Lightroom, but how does (say) RawTherapee compare?

This is what I did. Originally my parents were on Xubuntu, then I gave them an old Mac a few years ago, and now they are back on Linux Mint. My dad had no issues switching from iPhoto to Shotwell.
I see this recommended time to time and I just don't understand it. My mother doesn't understand even the first part of how computers work. If she says she can't find her file, and you ask here where she saved it, she'l tell you, "In excel", every fucking time. Linux is great but how often does a package fail to update and I spend 3 minutes untangling something? Pretty often. Give it to my mom and it just went form 3 minutes to now I have to go over to her damn house and listen to her fucking complain and fix her shit. She has an ipad and a kindle and she loves them and she can't break them no matter how hard she tries (and if she does she goes to the damn apple store, fuck)
Same here. My dad has been using Ubuntu for more than 5 years now.
My father has now been through two laptops and a NUC running Debian, with me supporting him remotely. 12 years now? He's much happier than my mother is with her Windows hardware.
This. I have an order of magnitude more issues with Windows (8.1, GWX, Anniversary Edition, oy vey!) than with Lubuntu (I support the same number of both box types for family). To wit, I'm typing this while restoring a WinX box to a point pre-Anniversary: Windows has become more of a bother than it's worth, sometime around Win8.
Darktable is where it's at. I also haven't used Lightroom for more than 5 minutes, but Darktable covers all my RAW developing needs. If you're not shooting for money, it should suffice. (If you ARE shooting professionally, it might(?) fall short, but I only shoot for myself.)
RawTherapee and the other Linux RAW software can't hold a candle to Lightroom. I don't even like Lightroom, but the Linux RAW editors are just not very good.

My advice to the OP is to tell them to buy a Mac, get Apple Care and let Apple Genius Bar deal with it.

> RawTherapee and the other Linux RAW software can't hold a candle to Lightroom.

This is just plain false. I used AfterShot Pro and I think it's better than Lightroom. The only reason that I switched back to Darktable is because I don't want to locked in the proprietary software.

I had a set up of my old computer with xubuntu for my mum for 1.5 years and had to learn that Linux is just not stable enough in the long run if installed for a novice user or as a "parent PC". Don't be naive here; even automatic updates will too often either break something or confuse users unfamiliar with computers. And you will need to be around to fix it or they won't be able to use that computer anymore.

I ended up buying her a second-hand MacMini for 110€ more than 2 years ago. Old enough that it still was a PowerPC version. It still works very well, never needed to fix something, it is fast enough for her use cases (e-mail, digital camera, some internet surfing), and she loves it. If things get messed up on OS X they do that in a "user friendly" way, and she (before being mostly annoyed by computers) has started to become quite proud if she can fix such minor issues by herself, or with only little guidance. I'd say she acquired some general computer literacy through using OS X, but not through using either Linux or Windows. She now likes Steve Jobs.

Same here. I bought a computer for my folks in around 2009 and installed Ubuntu on it. Some youtube and other tube sites, gnome-games, look at some photos off a camera/phone. That's almost all of what they need it for. The computers been running just fine for almost a decade now.
Same here.

Give them a Mint with MATE or XFCE; closer to Windows XP than anything else out there. Ublock + Chrome, make sure unattended upgrades are running and they are good to go.

You may want to add a dyndns entry and an ssh running with key-only auth, just in case you need to fix anything remotely for them.

It makes me smile that while proponents of censorship and blocking of parts of the Internet use the "Think of the children!" argument, I never hear anyone shouting "Think of the adults!"

Of course, in this case we're trying to protect people from themselves rather than the outside world, but still...

While I'm loathe to recommend a walled garden solution and not a particularly big Apple fan, this is exactly where such a solution shines. An iPad is perfect for this situation.
I feel conflicted about such advice too... but honestly I've resorted to using my iPad for stuff like streaming video just because it's safer out of the box. I figure if I'm doing that, I might as well suggest others do the same.
Story time:

My father complained of virus and malwares on his computer.

I came home, formatted his hard drive and re-installed windows.

I go to eat lunch with my mother in the kitchen, a few minutes later I hear "[baby], I have a virus on my computer!". WHAT?

The first thing he did was to google for "chrome" on internet explorer and use the first result. The first result is a google ads for a malware containing chrome. Had to reformat his computer one more time. I think that's the moment where he got it.

This might be the best argument for using an adblocker indiscriminately.

For whatever reason, the web got to this point where non-technical people get infected within minutes, whatever advertising revenue is lost by content creators isn't worth my headaches providing tech support to family members and friends.

It's truly pathetic that Google is selling ads that respond to a search for "Chrome" with malware.
to google for "chrome" on internet explorer

Is google being used as a generic verb here, in relation to Internet Explorer's default search engine?

I prefer to bing things on duckduckgo.
Bing is selling ads for "Chrome" searches, not Google. IE/Edge default to Bing.
(for the story my father used google.com to search for "chrome")
Chromebook.

I bought the cheap one (Lenovo) sometime ago. It has a good battery life, very lightweight and compact. I have seen the same being used by many people (in the same category). It is the most trouble free and productive piece of material there is. Ignore all these security software and Linux etc. Just hookup uBlock and Ghostery into the user's Google Chrome account and you're done.

Very similar here. Got a Chromebase for my Mum (77) who has previously had an original iMac (she loved) and a Windows 7 PC (which she tolerated). Both iMac and PC had issues, and I'd often have to fix stuff. There was a bit of a learning curve for her (cloud print is a mystery to her, not helped by it breaking about 2 weeks in and needing a powerwash to sort that), and she couldn't have Skype on it which was the one initial sticking point, but since her getting going with it I've not had any issues.

Indeed, a couple of weeks ago when she thought she'd killed it because she'd fallen for clickbait that then said she had viruses on the computer, she was pleasantly surprised that powering it up again showed it was fine. For the £220 it cost, it was money well spent - she can do what she needs/wants to online without issues, and TBH I think that a LOT of "normal computer use" people would be better off with one rather than the PC they think they need (usually when asked it turns out that internet and email with the odd bit of word processing and printing is what people do).

I am currently working on experimental Linux distribution for my parents that would be a bit ChromeOS-like.

Ideally for my mom ChromeOS device would be ideal. For my dad it would be not enough as it seems in your case. Maintaining my parents computer is something that always gets back to me. Now I am also living few hours worth of travel from them so it is even less convenient.

Older computer couldn't handle Ubuntu of the time. So always something was not working correctly. Updates on every system are constant source of headaches. My dad got used, but much more powerful machine. I installed Windows 10 for them thinking that Windows is now better and that with perpetual updates it will be out of trouble for me. I installed also Chrome Remote Desktop for service. My dad preferred Linux experience. I hoped that he just needs to get used to it. He was happy with Windows Store for a while, until few of the games he enjoyed playing failed in strange ways. It would not be that bad, but updates on Windows 10 are huge and with 20-30GB free space left after installation it does not update anymore. It only downloads the update, tries to update and fails - on every reboot. My dad bought an external HDD so probably it could be resolved. However he still would like to have Linux in there - old computer was very slow, but it did not fail in such magical ways. For now I plan to install Ubuntu for him and see how it will behave.

For my own learning experience and a bit of enjoyment I started working on my own Linux distribution. The most important thing for me is to have hassle-free updates like on Chromebook. I prepared squashfs image with Firefox and intend to have two partition scheme for rootfs. Updates would be then just download and restart away - completely automatic and in case of failure you would still have previous working image. I could test the image locally and optimize it for fun and profit. For now I base it on Gentoo to build lean system in a similar fashion to ChromeOS build.
