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.
