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