> I don't know why, but this doesn't result in the "Mountpoint not
empty" error (or any error/warning for that matter). I thought systemd
should be able to figure out the order of nested mounts, not sure why
it's not working here.
because systemd doesn't mount zfs mounts; zfs is a "magical" filesystem
that mounts itself because it's just so smart and special. All zfs
mounts are performed by 'zfs-mount.service' and systemd only creates
corresponding mount units after zfs performs the mounts (i.e. the
systemd mount units for zfs mounts only indicate the mount state, they
don't actually perform the mounting).

Title:
Mount unit fails but systemctl status shows success
Status in systemd package in Ubuntu:
Invalid
Bug description:
I have this mount unit
# cat /etc/systemd/system/srv-cctvstore.mount
[Unit]

On boot systemd thinks it is mounted:
$ systemctl status srv-cctvstore.mount

and the mount command seems to agree
$ mount | grep cctv
/dev/sda1 on /srv/cctvstore type ext4 (rw,relatime)
but the mountpoint is empty:
$ ls -al /srv/cctvstore/
total 1
drwxr-xr-x 2 root root 2 Dec 7 22:51 .
drwxr-xr-x 4 root root 4 Dec 7 22:51 ..
and umount thinks it is not mounted:
$ sudo umount /srv/cctvstore
[sudo] password for johann:
umount: /srv/cctvstore: not mounted.
journalctl doesn't report any funnies:
$ journalctl -u srv-cctvstore.mount
