-------------------------------------------------

I think we see the slowness also on experimental flows, same actions which takes a few seconds w/o mock takes 2 min when running with mock runner.
So we should probably give priority to checking the caching options.

> We've already known that setting up mock takes a while, but mock has some built-in caching features that should allow us to speed this up.
> We need to ensure those features are enabled by mock_runner.sh. The mock options to look at are:
> * root_cache_enable
> * yum_cache_enable
> Both these options should be set to true in the mock chroot config file.
> We've been using these option downstream in minimead and the vdsm build scripts, so they should be safe to use.
