We'd like to use a local repository for yum, so we don't download things 
from the SL mirrors multiple times. There's a recipe Troy wrote for 
doing this for SL3.0x at 
https://www.scientificlinux.org/documentation/howto/yum-change, but not 
for 4.x.

Could anyone supply such a recipe? I can guess at what to do, but with 
the new availability of the /etc/yum.repos.d/ directory and other 
changes in 4.x, I'm not sure what the best way to do it is.

Thanks very much,
Dan Halbert
