Description of problem: DISA STIG requires /var/tmp to be on a separate partition. A summary of an internal discussion about sizes: Right now /var is 15GB (not including some subdirs that already have their own partition). /var/tmp normally does not need to be that large, except for one known case - hosted-engine deployment, which creates a local VM with its disk image on /var/tmp. The ost-images project (used for ovirt-system-tests) already has /var/tmp on a separate partition, and it's set to 9220 MB. I suppose it was done as close-to-minimum, as we try to save space on CI there. So probably something slightly larger than that should be enough for all normal cases. We decided to have /var/tmp of 10GB, and make /var 5GB (instead of current 15) - this will keep the entire minimal storage needs unchanged, and should be enough for most cases.
