There was a good article posted on AFP548 yesterday about a way to run multiple software repositories (or branches) on one Mac OS X Server. This is a great idea and I wish I had thought of this when I was using it before. Basically you download ALL updates, duplicate the index file, and then change one (or more, if you want to have more than two repos) to mark which packages should be deployed to which group.
You could then use the ‘defaults write’ command (and send it through ARD if you have specific groups already set up) to tell which machines to go to which branch on the software update server.
If your a Mac sys-admin, then you should really be watching AFP548. When I was doing this stuff, I learned a VAST amount of stuff from this site. I still read it to keep up with the Mac admin community.
