Subject: tools/make-dnsmasq-conf: fix up some outstanding issues
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=9444001abc59f6eeb1ccb8acec19759378df8249;p=ceph-cm-ansible.git

tools/make-dnsmasq-conf: fix up some outstanding issues

1) hack domain_tag calculation for pok, suggest a better approach
2) fully-qualify the ip manipulation module names
3) host-record instead of host-address
4) create host-record in canonical order to avoid anyone worrying
