Fedora 22 systemd and ceph-deploy

[Owen Synge <osynge@suse.com>]

Dear all,

My plan is to make a fedora22-systemd branch. I will leave fedora 20 as
sysvinit.

Ok just done my first proper install of systemd ceph branch on fedora22.

I can confirm most of the issues.

I am giving up for the day, but so far applying SUSE/opensuse code to
Fedora ceph-deploy code in ceph-deploy has helped a lot.

    cp /usr/lib/python2.7/site-packages/ceph_deploy/hosts/suse/mon/* \
      /usr/lib/python2.7/site-packages/ceph_deploy/hosts/fedora/mon/

(Running on suse version patched release)

It can now set up the mon daemons correctly its self.

I will look into the udev rules, tomorrow morning, and remove some more
fedora hard coding to "sysvinit".

Best regards

Owen
