The OSDs are normally mounted and started via udev, which will call
'ceph-disk activate <device>'. The missing piece is teaching ceph-disk
how to start up the systemd service for the OSD. I suspect that this can
be completely dynamic, based on udev events, not not using 'enable' thing
where systemd persistently registers that a service is to be started...?
