I'm not entirely familiar with the details of mountall; but it looks
like it just ignored the fstab entry for the root partition in this
case, together with all of its options, and merely made the root
partition read-write.

So if you have multiple installations on your system, you could end up
booting the wrong one in the worst case. Also, having a wrong UUID in
fstab means that you could never rebuild your initramfs, as that would
propagate the wrong UUID there. I actually wonder how your system
managed to boot like that before? Every other package in -updates or
-security triggers an initramfs update, after all..

Thanks,

Martin

Title:
  does not boot with broken UUIDs in fstab

Status in systemd package in Ubuntu:
  Won't Fix

Bug description:
  After successful upgrade from kubuntu 14.10 to 15.04, the system hangs during boot and never reaches the login screen. When grub menu entry "Ubuntu, with Linux 3.19.0-15-generic (upstart)" is selected, the system boots normally.
  It turns out that the /etc/fstab uuids for the / and swap partitions are not correct. Once corrected and set to the values from /dev/disk/by-uuid/, booting is possible using systemd.

  fstab had been edited manually in the past but there were no problems
  until the upgrade to 15.04.
