The zone name (attached to a cluster controller) can still be changed when it contains in-use nodes and DNS is managed.

Small Q/A failure: renaming an accepted nodegroup that has no interfaces will oops. See bug 1077075 (and don't get confused by the similarity in bug numbers...)

The Q/A failure has been fixed in both the trunk and 1.2 branches.

This bug was fixed in the package maas - 1.2+bzr1349+dfsg-0ubuntu1

---------------
maas (1.2+bzr1349+dfsg-0ubuntu1) raring; urgency=low

  * New upstream bugfix release. Fixes:
    - The DNS configuration is not created if maas-dns is installed after
      the DNS config has been set up (LP: #1085865).
    - IPMI detection ends up with power_address of 0.0.0.0 (LP: #1064224)
    - Main page slow to load with many nodes (LP: #1066775)
    - maas-cluster-controller doesn't have images for
      provisioning (LP: #1068843)
    - Filestorage is unique to each appserver instance (LP: #1069734)
    - import_pxe_files does not include quantal (LP: #1069850)
    - maas-cli nodes new incomplete documentation (LP: #1070522)
    - DNS forward zone ends up with nonsensical entries (LP: #1070765)
    - The hostname of a node can still be changed once the node is in
      use. (LP: #1070774)
    - The zone name (attached to a cluster controller) can still be changed
      when it contains in-use nodes and DNS is managed. (LP: #1070775)
    - Duplicated prefix in the url used by the CLI (LP: #1075597)
    - Not importing Quantal boot images (LP: #1077180)
    - Nodes are deployed with wrong domain name. (LP: #1078744)
    - src/maasserver/api.py calls request.data.getlist with a 'default'
      parameter. That parameter is not supported by Django 1.3. (LP: #1080673)
    - API calls that return a node leak private data (LP: #1034318)
    - MAAS hostnames should be 5 easily disambiguated characters (LP: #1058998)
    - URI in API description wrong when accessing machine via alternative
      interface. (LP: #1059645)
    - Oops when renaming nodegroup w/o interface (LP: #1077075)

  * debian/maas-dns.postinst: Call write_dns_config (LP: #1085865).
  * debian/maas-dns.postinst: fix permissions and group ownership of
    file /etc/bind/maas/named.conf.rndc.maas. (LP: #1066935)

  [ Julian Edwards ]
  * debian/maas-region-controller.install: Remove installation of maas-gc; it
    is no longer required as upstream no longer stores files in the filesystem.
    (LP: #1069734)
  * debian/maas-cluster-controller.postinst: Ensure that /etc/maas/pserv.yaml
    is updated when reconfiguring. (LP: #1081212)

  * debian/control:
    - maas-cluster-controller Conflicts with tftpd-hpa (LP: #1076028)
    - maas-dns: Conflicts with dnsmasq
    - Drop Dependency on rabbitmq-server for maas-cluster-controller.
      (LP: #1072744)
    - Add conflicts/replaces for maas-region-controller to
      maas-cluster-controller.
  * debian/maas-cluster-controller.config: If URL has been detected, add
    /MAAS if it doesn't contain it. This helps upgrades from versions where
    DEFAULT_MAAS_URL didn't use /MAAS.
  * Install maas-import-pxe-files and related files with
    maas-cluster-controller, as well as configure tgtd, as
    maas-region-controller no longer stores images. Thanks to Jeroen
    Vermuelen.
