Well, it seems I spoke to soon. Not sure what logic the udev rules use
to identify ceph journals, but it doesn't seem to pick up on the
journals in our case as after a reboot, those partitions are owned by
root:disk with permissions 0660.
Adding 'ceph' user to the 'disk' group oddly enough isn't sufficient.

sdc5 and sdc6 are the journals for sda1 and sdb1. Journal disk here is
a Intel 520-series 60GB SSD, shared with the host OS, formatted with a
MS-DOS disklabel. I'm not sure what partition type the Ceph udev rules
expect.
