[pve-devel] [PATCH V3 4/5] Mask the SysV scripts and enable our systemd service.

[Wolfgang Link]

This is important to control the exact start-up of ceph at boot.
We have the ceph.conf in the pmxcfs so pve-cluster.service must startup first.
The ceph.sevice is a link to the old SysV script.
For more information see http://tracker.ceph.com/issues/18305 .
