This reverts commit 0194a44d63c613065bb5c55d50470881c00563c2 because
it breaks udisks on 13.10 (e.g. running "udisks --enumerate" will
print "Unit udisks.service failed to load").
(cherry picked from commit d7daf1a47f0d3d759555a3f0a0f09398c69c6b28)
Latest update to udisks in 344f2e65 broke it for me. Fix it by doing the
following:
- Add udisks.service to /etc/systemd/system (via systemd.packages)
- Fix path to udisks-daemon in udisks.service (libexec/ instead of lib/)
