I think mock with no parameters will use /etc/mock/default.conf, or you 
can choose to use a particular one by specifying it on the command line.

Mock erases and rebuilds the /var/lib/mock build root every time you do 
a mock rebuild. This is how it can be sure that the rebuild process 
isn't sneakily pulling in files/libraries that can not be assumed to be 
present.

Use it to monitor you CPU/disk/network usage, realtime; it gives a 
better idea that something is indeed happening.

Installs the minimal build system packages in a mock chroot jail. Then 
it installs the buildrequires specified in the .srpm that you are 
getting mock to test build.

Look in /var/lib/mock/fed.../result/ files to see what it did.

You need a caching mechanism to speed up the process of mock 
reconstructing the build root each time you run it. (Either squid proxy, 
or rsync/mirroring of the site).
