First of all, sorry for my recent absence, I was hoping to spend some time on Arch over Christmas, which I didn't.
Anyway, today's systemd upgrade causes a problem which I was only able to solve by downgrading:
When systemd launched kdm.service, X started, but the kdm greeter never appeared - instead X just sat there with the busy mouse pointer. systemctl stop kdm.service hung too, I could only kill -9 the X process.
When I downgraded to 196-2, the greeter started immediately after the systemctl daemon-reexec in post_upgrade. I have no idea where to start, so any help is appreciated.
Even worse: After the downgrade, systemctl start /boot (and thus the automounter) didn't work, I had to mount /boot manually.
