virtualisation.fileSystems.<name>.overlay.useStage1BaseDirectories
If enabled, lowerdir, upperdir and workdir will be prefixed with /sysroot.
Disabling this can be useful to create an overlay over directories which aren't on the real root.
Disabling this does not work with the scripted (i.e. non-systemd) initrd.
