I use colmena[1] to manage one nixos configuration for multiple machines: - laptop - desktop - server - rpi nas

I also wipe my entire rootfs every boot with a zfs snapshot rollback[2] using the impermanence module[3] to keep specific stateful data one one of two datasets with regular snapshots: one is backed up with zfs send, the other is just for cache between reboots.

It took a little puzzling to get started, because I didn’t know about the impermanence module at first, so I built my own hacky solution. But I really love this setup. And the way I don’t have cruft to clean.

Also my backups are so much smaller now :’-)
