Actually, you could just look at /etc/yum.repos.d. In there, you can also
check to see if the repo is enabled, or if there's includes or excludes.
We do that here, because there are systems we do *NOT* want some things
updated without someone doing it manually, like the ones with very old
NVidia cards, where we have to manually rebuild the proprietary drivers,
or production systems, where the teams want to test the updates before
they go into production.
