Ceph » rgw

Relevant snippet:

# mapped to this host?
host=`ceph-conf -n $name host`
if [ "$host" != `hostname` ]; then
    continue
fi

Depending on how a server is configured, the output of "hostname" can be different.
Given a hostname "test.example.org", sometimes it'll output "test" - other times it will output "test.example.org".

This can be confusing for the user relative to the configuration that is expected in ceph.conf.
Should the "host" value be the complete fqdn ("hostname -f") or the hostname ("hostname -s") ?

Relevant snippet:

[client.radosgw.gateway]
  # Need this parameter for the default apache2 packages
  rgw print continue = false

  rgw enable usage log = true
  rgw enable ops log = true
  rgw usage log tick interval = 30
  rgw usage log flush threshold = 1024
  host = rgw01      # <---------
  keyring = /var/lib/ceph/radosgw/keyring.rgw
  rgw socket path = /tmp/radosgw.sock
  log file = /var/log/ceph/radosgw.log

I propose that we maintain compatibility with the existing init script but be a bit more permissive by allowing both the fqdn (hostname -f) and the hostname (hostname -s).
