boot.initrd.systemd.root
NixOS option
Controls how systemd will interpret the root FS in initrd. See kernel-command-line(7). NixOS currently does not allow specifying the root file system itself this way. Instead, the fstab value is used in order to interpret the root file system specified with the fileSystems option. If root shall be omitted, set this option to null.
