Ceph recently hosts systemd service files in their tree: https://github.com/ceph/ceph/tree/master/systemd They should be tested and installed with the current release. I'll do this in the near future if no one else hasn't already and states it here. Reproducible: Always
I'm not using systemd myself, if you can provide sane systemd-unit-file support. I would more than happy to take it. note, upstream's systemd script source file /etc/sysconfig/ceph which is rather redhat specific? and does not exist under Gentoo.
There is a working ebuild for ceph-0.94.1 which supports systemd. See bug #550892.
