Systemd mount configuration file must have a name that match the mount
point directory they control. So for instance, if a mount file contains
[Mount]
...
Where=/mnt/my-data
The file must be named `mnt-my\x2ddata.mount`, or systemd will refuse to
honour it.
If this config file contains an [Install] section, it will silently fail
because the unit file is not escaped properly when systemctl is called.
To fix that, make sure paths are escaped through `shlex.quote`.
