Just to throw a few thoughts into the discussion:

How about making shadow images relative to the original install CD 
available? The user would merge it with her install CD already 
available to get a current install CD. This way, you'd have always a 
current CD handy - if you ever tried to install something like Mac OS X 
10.2.8 trough 10.2.0 -> 10.2.1 -> ..., you probably know what's the 
benefit. Even with using the last combo updater, I had to install no 
less than 8 patches right after the initial install. Similar 
considerations apply to Darwin once there are updates available.

This would encourage enhancing the update mechanism as well as you 
would use a full system installation CD to upgrade a existing system. 
Only the diffs between install CD and the system on HD would be 
touched, of course.

A solution based on distributing binaries is to be preferred, IMHO, 
since this reduces hassle with adjusted/modified/customized build 
environments. Plus, it can be used when distributing closed source.
