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
Enable only security updates checks(yum-plugin-security has to be installed)
#Dorin on 03.08.2017
USE_YUMSEC="true"
#Dorin 09.03.2018 changed to false, there is a similar check in icinga
#ENABLED="true"
ENABLED="false"
