Jeroen T. Vermeulen has proposed merging lp:~jtv/maas/prep-config-migration
into lp:maas.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:
https://code.launchpad.net/~jtv/maas/prep-config-migration/+merge/104203
As per the migration plan. This prepares the Config and ConfigManager classes
for migration on Tuesday 2012-04-08.
While I was at it, I also added the required DefaultMeta class to the other
maasserver models. Saves adding it in every migration prep branch and removing
it again in every actual migration branch.
As part of keeping the migration simple and minimizing each model module's
exposed interface, I removed the config_manager reference and just defined the
ConfigManager singleton in its usual place: Config.objects.
