No, it would have been impossible for any desktop image (even pending)
to contain the new systemd on the 31st of January.

The first image that contains the new systemd is from 20190204 or later.

** Changed in: systemd (Ubuntu Disco)

Bug description:
  [Impact]

  Mounting manually a network share (NFS) and masking it breaks the state of other units (and their dependencies).
  Casper is masking a mounted NFS share, blocking the normal boot process as described in the original description, but the issue comes from systemd.

  [Test Case]

  - NFS mount point at /media
  root@iscsi-bionic:/home/ubuntu# mount | grep media
  10.230.56.72:/tmp/mnt on /media type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.122.127,local_lock=none,addr=10.230.56.72)

  - Test mount point (/test) defined in /etc/fstab:
  root@iscsi-bionic:/home/ubuntu# cat /etc/fstab |grep test
  tmpfs /test tmpfs nosuid,nodev 0 0

  1. If media.mount is not masked, everything works fine:

  root@iscsi-bionic:/home/ubuntu# mount | grep test
  root@iscsi-bionic:/home/ubuntu# systemctl status media.mount | grep Active
     Active: active (mounted) since Thu 2018-11-15 16:03:59 UTC; 3 weeks 6 days ago
  root@iscsi-bionic:/home/ubuntu# systemctl status test.mount | grep Active
     Active: inactive (dead) since Thu 2018-12-13 10:33:52 UTC; 4min 11s ago
  root@iscsi-bionic:/home/ubuntu# systemctl start test.mount
  root@iscsi-bionic:/home/ubuntu# systemctl status test.mount | grep Active
     Active: active (mounted) since Thu 2018-12-13 10:38:13 UTC; 3s ago
  root@iscsi-bionic:/home/ubuntu# mount | grep test
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)
  root@iscsi-bionic:/home/ubuntu# systemctl stop test.mount
  root@iscsi-bionic:/home/ubuntu# systemctl status test.mount | grep Active
     Active: inactive (dead) since Thu 2018-12-13 10:38:32 UTC; 3s ago
  root@iscsi-bionic:/home/ubuntu# mount | grep test

  2. If media.mount is masked, other mounts are failing:

  root@iscsi-bionic:/home/ubuntu# systemctl mask media.mount
  Created symlink /etc/systemd/system/media.mount → /dev/null.
  root@iscsi-bionic:/home/ubuntu# systemctl start test.mount
  Job for test.mount failed.
  See "systemctl status test.mount" and "journalctl -xe" for details.
  root@iscsi-bionic:/home/ubuntu# systemctl status test.mount | grep Active
     Active: failed (Result: protocol) since Thu 2018-12-13 10:40:06 UTC; 10s ago
  root@iscsi-bionic:/home/ubuntu# mount | grep test
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)
  root@iscsi-bionic:/home/ubuntu# systemctl stop test.mount
  root@iscsi-bionic:/home/ubuntu# systemctl status test.mount | grep Active
     Active: failed (Result: protocol) since Thu 2018-12-13 10:40:06 UTC; 25s ago
  root@iscsi-bionic:/home/ubuntu# mount | grep test
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)
  root@iscsi-bionic:/home/ubuntu# systemctl start test.mount
  Job for test.mount failed.
  See "systemctl status test.mount" and "journalctl -xe" for details.
  root@iscsi-bionic:/home/ubuntu# mount | grep test
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)
  root@iscsi-bionic:/home/ubuntu# systemctl stop test.mount
  root@iscsi-bionic:/home/ubuntu# mount | grep test
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)
  tmpfs on /test type tmpfs (rw,nosuid,nodev,relatime)

  [Regression potential]

  Minimal. Originally, one failing mount point blocked the processing of
  the rest due to how the return codes were handled for every line in
  /proc/self/mountinfo. This patch removes this "dependency" and keeps
  the failure local to the affected mount point, allowing the rest to be
  processed normally.
