Thanks, the light is starting to dawn.
Attachments is a slightly different beast; it appears to be a pseudo-singleton package. It's only instantiated once, when it's mounted at /attachments during the dotlrn install, and then that one copy is mounted up each time dotlrn-forums is added to a new community.
I had thought that becuase it's different, I would need to manually mount it up each time, but it sounds like you all are saying that won't be necessary. So I'll go off and look into that.
