Well state includes (for most configs I’ve seen) the persistence of user paswords, known_hosts, wifi auth, /home, /var, nix-channels, nixos-generations, disk encryption passwords, secrets in general, docker/podman, VMs, …
Except for my home directory, I have a little bit state on my machine, ssh host keys, WiFi credentials, journal logs (I almost want to remove this, but I bet that would bite me in the ass one day)
The root partition is a tmpfs ram disk, and everything not saved in a separate partition, and either mounted or symlinked on to my root partition is lost at shutdown and regenerated at boot. Its less than a second extra to boot, and it uses about 16MB extra memory. Everything is made very convenient through the impermanence nix module and the sops nix module
Never had to use state so far, so I don’t know. Makes some sense for a personal config I guess, but afaic it’s never been necessary
