Well, there's @core and @base each of which installs some
smallish
amount of stuff. It's actually more like 800 megs, which is a long way
from where you want to be. But we've had a problem with an ill-defined
minimal install for a while now so perhaps you are used to this. You
can just start with that and remove things you don't want.
To be fair - if you know what you're doing you can yum remove a lot of
stuff in
%post to make your installs very minimal.
You can get an install stripped pretty far down, actually.
