I'm indifferent to agent vs. agent-less. I *believe* that having a ceph-private distribution is easier/simpler/more reliable than trying to layer over some other system (ansible, salt, etc.) [i.e., I agree with John]. But this isn't a strongly held belief. I'm *metaphysically certain* that whatever distribution scheme is adopted that it not be optional. A large barrier to adoption of Ceph today is the lack of "middle-ware" that handles infrequent operational events (node addition/removal, media failure/recovery, migration, etc.). IMO, this middle-ware will have to be a standard part of Ceph, i.e., fully functional "out of the box" without site-specific twiddling (though having a mechanism to insert site-specific stuff is fine with me, it just can't be *required*). In my mind, the distribution scheme is the next step in the evolution of Ceph-mgr.
