Comment 32 for bug 1322302

Note that bug 1317680 may be a potential issue here. If you end up in the situation that you've previously synced the same release from both a daily and a released stream, then an attempt to create a container will be unambiguous and thus fail. In that bug the issue was that the user had manually done it locally. Here, the problem may be that Juju trips itself up by ending up in that situation, if Juju mixes use of released and daily streams.

I suppose a wider issue here is that we don't currently have a good answer inside simplestreams for syncing images from multiple streams into the same pool.
