> After implementing speedup improvements for mock_runner.sh (Specifically enabling it to deploy the chroot by extracting a tarball as opposed to installing it with yum every time), I started monitoring run times for vdsm check_patch jobs.
> I've noticed that jobs that are running on the old slaves (fc24-vm*) seem to initialize mock faster then ones running on new slaves (vm*) - 17seconds vs 57 seconds respectively.
> I suspect this may be because the older slaves have a different FS mounted on /var/lib/mock
