I just got around to a fresh NixOS install and I couldn't be happier as I've been able to do practically everything via Codex while keeping things concise and documented (given it's nix, not a bunch of commands of the past).
I recently had a bunch of breakages and needed to port a setup - I had a complicated k3s container in proxmox setup but needed it in a VM to fix various disk mounts (I hacked on ZFS mounts, and was swapping it all for longhorn)
As is expected, life happens and I stopped having time for anything so the homelab was out of commission. I probably would still be sitting on my broken lab given a lack of time.
