Description: mounts that start with a slash then dot such as /.snapshots or /.subvols are not mounted by systemd 184-2 even though the entry is correct in /etc/fstab and can be mounted manually using the mount command.

This worked with previous systemd versions



Additional info:
* package version(s)

systemd 184-2

* config and/or log files etc.

/etc/fstab from 2 different systems
/run/systemd/generators/.<mountpoint>.mount from 2 different systems

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
JOB = Pending job for the unit.

14 units listed.



Steps to reproduce:

Create an entry in fstab for a mount on a hidden directory under /
Reboot and note that while the .mount file is generated under /run/systemd/generators the unit file doesn't show in systemctl and isn't mounted.
