Impermanence in NixOS is where your root directory gets wiped every reboot (such as by mounting a tmpfs to /). Such a setup is possible because NixOS only needs <code>/boot</code> and <code>/nix</code> in order to boot, all other system files are simply links to files in <code>/nix</code>. <code>/boot</code> and <code>/nix</code> still need to be stored on a hard drive or SSD.
