I finally found some time to tinker around and refactor my nix configuration and I’m reckoning to go for btrfs instead of ext4.

After some research I would be interested in knowing:

  • how your subvolume layout (flat vs. nested) looks like?
  • which snapshot utility (snapper, timeshift, …) you use?
  • which subvolumes to you actually snapshot (and how do you handle the nixos directory)?
  • is snapshotting automated (e.g. is it triggered by some kind of event or run periodcially through cron and/or systemd timers etc.)?
  • if you use disko, how is the experience?
