** Description changed: - netbooting the bionic live CD[1] over NFS goes straight to maintenance - mode : + [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.
