Well, Lennart says explicitely that with systemd and /usr mounted on its own file system things like audio, or printing or plug'n'play will not work and that he does not care as they were broken anyway. Maybe in some of his warped universe as I can assure you that up and including Fedora 14, and with /usr like the above, all these things do work just fine.
Essentially, you have to ensure that everything called during the boot cycle up until the point that /usr is mounted,
In Fedora 14 instead of weird excuses you run in /etc/init.d/udev-post
/sbin/udevadm trigger --type=failed --action=add
Most likely ensuring that something of that sort is present in an appropriate place of a boot sequence would solve the issue in practice.
So, then it's a cost-benefit ratio, and weigh that at against the usage case of separate /usr (which is.... ?)
I do not have statistics and you do not have them either. I have seen quite a few in various places. So how much of such breakage is ok?
