PS: long time ago i opened a report for that, but never got any reaction there... https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1765765 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1755863 Title: netbooting the bionic live CD over NFS goes straight to maintenance mode : Status in systemd: Unknown Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: In Progress Status in systemd source package in Bionic: In Progress Status in systemd source package in Cosmic: Triaged Status in systemd source package in Disco: Fix Released 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 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.

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.
