I am in the process of setting up ZLM 7.3, and using zlmmirror to bring down the channels for SLES/SLED 10 and 11 from nu. I was wondering if someone could give me a better description of each of these channels? I can't seem to find that documented anywhere.

-Updates (self explanatory...)
-Extras (only exists for SLES/SLED 11?)

I'm sure i am probably overlooking some place where there is a detailed explanation, so if that is the case, I'm sorry for asking the obvious.
