1# Necessary system state {#ch-system-state}
2
3Normally — on systems with a persistent `rootfs` — system services can persist state to
4the filesystem without administrator intervention.
5
6However, it is possible and not-uncommon to create [impermanent systems], whose
7`rootfs` is either a `tmpfs` or reset during boot. While NixOS itself supports
8this kind of configuration, special care needs to be taken.
