Except it's... not quite correct. getent performs NSS resolution, not DNS resolution, so its output depends on the value of the hosts field in your /etc/nsswitch.conf, which could be set to something fun like LDAP or…
Not at all. I'm referring to the structure of the Alpine packaging, especially around boot scripts, that hardcodes busybox in a number of places and makes it difficult to package an alternative without workarounds -…
Your information is incorrect. "Avoiding spinning up new processes" is incorrect characterization of s6. Processes are not a scarce resource; spawning a process is not a costly operation in the context of process…
There is no good solution for servers that, mistakenly, background themselves; the practice of backgrounding itself comes from a time where supervision was not as widely known as it is today, and nowadays there is no…
You need to read the archives of the supervision mailing-list at list.skarnet.org, as well as http://skarnet.org/software/s6/overview.html - there is a lot of value in process supervision, it's just that most people who…
I agree with Jonathan on everything here, with the additional caveat that the Go runtime is particularly heavy, and thus not really suitable for low-level system software (which should use resources sparingly, leaving…
Still in active development too. :) And no, Jonathan, I haven't heard anything from TrueOS people. Which is a shame, because if a distribution is being built today, with no existing legacy service script base to cater…
I see nothing there that can't be achieved by a simple supervision suite. s6, nosh, even runit provide those features; the extra complexity of systemd isn't needed at all. If even embedded developers are getting pulled…
Honestly, the people who use Busybox are probably aware of the problems - political as well as technical - with systemd, and most likely not using systemd in the first place because it's not exactly a good choice for…
But how would you go with restoring such an image? It won't be instant, there will still be a window where the service manager is continuing its work but the image hasn't been restored yet. One way or the other, you…
You seem to dislike the idea of asking for notification support in the daemons themselves. Granted, it's impractical, but it's the only way to avoid race conditions which are rare for most services, but very real for a…
As Jonathan said: the reason for the compilation phase is efficiency. The information in the compiled database is organized for fast loading and immediate access to the complete dependency tree. And yes, efficiency is…
Yes, that was exactly the idea behind s6-fdholder-daemon: set up a central server to keep fds open when you need to restart a process. The old process stores the fd into the fdholder, then dies; the supervisor starts…
Note that: - You do not have to follow the slashpackage convention to use or build s6. You can configure it out. - You do not have to write your init scripts in execline. Any scripting language, including the shell,…
