Bug#788303: systemd: Hangs indefinitely on >90% of reboot attempts

[Frank Heckenbach]

As a work around, I've put the following in
/etc/systemd/system/workaround-788303.service and activated it with
systemctl enable workaround-788303

This seems to work for me for now. Of course, I'd prefer a real
bugfix. (And so should the systemd author, seeing how much he hates
using the shell ... ;)
