I have NixOS running on mine and I write everything in comments in my configuration.nix. Usually I’ll write notes about why I set a certain option above the line where I do it but I also have a section at the start that describes anything to be aware of if I’m moving this configuration to another machine. For example “This assumes a drive is mounted on /mnt/backup0”

100%. This is exactly why I switched my home server over to NixOS and would struggle to go back. I used to reinstall all the time but now there really isn’t any need to, since I can just look at my configuration.nix file and know everything that’s installed, running and configured on my system. Whereas using any other distro I’m like WHAT ON EARTH IS RUNNING ON HERE?

This week I realised my Mastodon instance was severely out of date because I was using nix flakes and didn’t autoupdate but now that’s been fixed 😄

I’m currently looking to connect an NVMe SSD to a Pi 4 I have in a differences location to finally have proper 3-2-1 backups. I’m trying to find a NVMe to USB adapter that will work though.
