# NixOS {#sec-nixos-state}
NixOS itself obviously needs `/nix` to be persistent, so the system environment
can be linked from the nix store during activation.
## `/nix` {#sec-state-nix}
Moreover, `/boot` should also be persistent, as it contains the kernel, initrd,
and the command-line determining the system environment's path in the nix store.
NixOS needs the entirety of `/nix` to be persistent, as it includes:
- `/nix/store`, which contains all the system's executables, libraries, and supporting data;
- `/nix/var/nix`, which contains:
- the Nix daemon's database;
- roots whose transitive closure is preserved when garbage-collecting the Nix store;
- system-wide and per-user profiles.
## `/boot` {#sec-state-boot}
`/boot` should also be persistent, as it contains:
- the kernel and initrd which the bootloader loads,
- the bootloader's configuration, including the kernel's command-line which
determines the store path to use as system environment.
## Users and groups {#sec-state-users}
