NixOS

Impermanence
This post covers both EFI and legacy boot setups.
One fairly unique property of NixOS is the ability to boot with only /boot and /nix. Nothing else is actually required. This supports doing all sorts of weird things with your root file system.
One way is to do like Graham’s post “erase your darlings” describes and empty your root file system each boot using ZFS snapshots. This way have some cool things that you could do on top of his setup, such as doing snapshots when it’s running and roll-back to empty on boot.

NixOS
Linux
ZFS
So for a long time I have wanted to replace my file server, because it’s an old HP Microserver that is really slow. And at the same time I have had this beast of a desktop tower PC that I haven’t used with a Xeon and 32GiB ECC memory that has just been turned off due to noise. The obvious solution is to re-purpose that install and move it to a location where noise doesn’t matter, e.
