CHECK_ONLY="true" (yum checks every day if there is a new update and send an email at hpss-admin@lists.kit.edu)
The administrators decide if the updates have to be applied or not
Since the updates are not automatically applied we can also have:
#EXCLUDE="kernel* openafs* *-kmdl-* kmod-* *firmware*"
so that the administrators are informed about all existing updates

MISCELLANEOUS
yum repolist
yum --enablerepo=sl6x-security update
