Ceph

Testing a reasonably recent ceph-10.0.2 on openSUSE Leap 42.1, my OSDs weren't mounting. I tracked this back to /usr/lib/systemd/system/ceph-disk@.service which invokes `flock /var/lock/ceph-disk /usr/sbin/ceph-disk --verbose --log-stdout trigger --sync %f`. This in turn results in:

ceph-disk: main_trigger: Namespace(dev='/dev/sdb1', func=<function main_trigger at 0x7fa6ebf6b050>, log_stdout=True, prepend_to_path='/usr/bin', prog='ceph-disk', statedir='/var/lib/ceph', sync=True, sysconfdir='/etc/ceph', verbose=True)

The important part is:

Traceback (most recent call last):
  File "/usr/bin/ceph-detect-init", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

This is fixable by installing python-setuptools, suggesting that package needs to be added to the RPM Requires and, I assume, the Debian Depends.
