Usually works fine. However, it is somewhat less safe, the system is in
an inconsistent state until you reboot, with no easy way to distinguish
which processes are using new and old versions of libraries. 

Also, and best, if you're using btrfs, systemd will make a snapshot,
and so you'll get either an upgraded system... or if there's a problem,
no change. Unfortuantely, there are _other_ problems with btrfs, so
that's not the default (or recommended). Possibly we'll have this same
functionality with LVM in the future.
