I am not convinced that the cgroup issue was the only issue here, but since this is a single physical I can't easily go back in time to test further.
Either way the changed summary is backwards. Once repartitioning was completed systemd fails to boot if the /dev/cgroup fstab entry IS present. The one obvious thing we have is a case where do-release-upgrade should have removed the /dev/cgroup fstab entry and did not. A better summary might be something like: + boot fails with systemd when /dev/cgroup fstab entry is present On Thu, July 2, 2015 2:44 am, Martin Pitt wrote: >> cgroup /dev/cgroup cgroup defaults 0 0 > > Erk -- that's what broke the boot after all?
