A new internal config option `fileSystems.<name>.early` is added to indicate that the filesystem needs to be loaded very early (i.e. in initrd). They are transformed to a shell script in `system.build.earlyMountScript` with calls to an undefined `specialMount` function, which is expected to be caller-specific. This option is used by stage-1, stage-2 and activation script to set up and remount those filesystems. Options for them are updated according to systemd defaults.
