That's a good idea for the case where ceph-osd is proactively 
identifying a failing drive.  I'm also thinking about the case where we 
come back from a reboot and a drive is sufficiently unreadable that 
ceph-disk doesn't see the OSD partitions and ceph-osd never gets 
started, or the OSD's local filesystem is unmountable.  Because the 
keyring lives on that local filesystem, OSDs couldn't phone home in that 
case, even to report a failure.
