In Search of a "Zero Toil" HomeLab: Immutable Linux, ZFS, WatchTower and Keel (blog.gripdev.xyz)

Over the last year I've been rebuilding my home lab to avoid all the toil of updates and maintenance

I'm currently managing development VMs (mostly Fedora Cloud) using Ansible on a Proxmox hypervisor and i'm mostly happy with how it works. I'm interested in experimenting with immutable OS's , the most immediate difference I see is that I'd have to start using Butane instead of CloudInit. Can anyone with experience comment on the pros and cons ? Right now, I really do everything in Ansible, including creating the VMs from a proxmox clone template.

surprised a git repo wasnt posted in regards to the whole setup
