Comment 4 for bug 1382190

Also FTR it's not the static IP work that left LXCs without PTRs, it's the fact that we used to pre-generate the whole zone with fake host names and used CNAMEs for any nodes that MAAS knew about. That came with a raft of its own problems (some charms failed because CNAMEs-> IP -> reverse lookup -> different A record) and IP ranges were limited to /16 because otherwise it took a long time to write the zone every time.

There is no doubt that juju needs to move to use the new API.
