[Yum] What is "non-caching mode" and how do I get there?

[Jeff Sheltren]

Hi Joe, out of curiosity what gets output when you increase the debug/error
output from yum (using the -d -e flags)?  I think something like 'yum -d 5
-e 5 update' will print out a bunch more 'crap'.  Maybe this will help trace
the problem.
