I dug into this more on the server that failed to upgrade properly to see if the server would work properly after switching back to systemd. Please recall this was after a backup and restore with a much simpler partitioning scheme. It still would not boot.
I ended up finding this line in my fstab: cgroup /dev/cgroup cgroup defaults 0 0 This was not a line I added. I believe it may be a remenant from an old release which the upgrader did not comment out. The server began its life with Ubuntu 10.04. Once I commented that cgroup line out the system booted with systemd in place. Since I doubt this will ever get to a complete state please close the bug. -- 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/1460794 Title: systemd does not boot with a separate /usr partition Status in systemd package in Ubuntu: Incomplete Bug description: I recently upgraded a server from 14.10 to 15.04. The upgrade claim to have worked but the system could not boot afterwards. Basically when you attempt to reboot you end up at an emergency maintenance prompt early in the boot process. After a lot of digging one of the messages in the logs gives: systemd[1]: /usr appears to be on its own filesystem and is not already mounted. This is not a supported setup. Some things will probably break (sometimes even silently) in mysterious ways. Consult http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken Basically systemd cannot deal with /usr being on a separate partition. That needs to be fixed or systemd should not be used for upgrades with a separate /usr partition. This is related to bug 1460790 but asking for systemd to actually be fixed. Please see bug 1460790 if you are looking for a work around on this issue.
