This is a symptom of Python < 2.7, but you say Ubuntu 12.10; are all the 
hosts running 12.10?  Have you manually configured the hosts to use 
Python < 2.7?

If the hosts are running < 2.7 on purpose, there's a fix for this in 
git; see http://tracker.ceph.com/issues/5086, but it shouldn't be 
happening on 12.10.

If you're running on 12.10 with ceph-deploy, you're using Upstart, so 
you probably want upstart commands (start ceph/stop ceph)

Not directly; it's inferred from the presence of directories in 
/var/lib/ceph.  You can, of course, still add configuration options to 
ceph.conf, it's just that you don't have to specify daemon 
location/address there as you used to.
