The ceph-osd package is only required on nodes hosting the CephOSD
service, but the package's presence on other nodes may interfere with
software updates. That's because some distros distribute Ceph software
in different channels, and not all nodes have access to the ceph-osd
channel.
There are two parts to the fix, and the first is an enhancement to the
yum update process. The process detects when the ceph-osd package is not
required, and removes the package from the node.
The second part takes ceph-osd out of the default list of packages
needed by puppet-ceph. The ceph-osd package is listed only on the nodes
hosting the CephOSD service.
