Note that we run udevd in its own mount namespace through MountFlags=,
and this means no mounts will ever appear on the host anyway.
Note that it is sufficient to mark mounts as "auto,nofail" in
/etc/fstab to make sure they are mounted automatically as they appear
without making the boot wait for it.
