This does not look right either. I'd rather expect to a) set
DefaultDependencies=no for these special mounts so that they are left
at shutdown and b) ignore them in the final killing spree if needed
(unless happens already).

If I as user do "systemctl stop /dev/pts" I expect it to
unmount /dev/pts not fake "dead" state.
