mock needs some attention to set up. There's a bug in the newest
release that seems to force the use of the fully qualified path to the
.spec file or SRPM you're using, which was driving me nuts until I
worked it out.It also uses the CentOS mirror repositories, by default,
and needs tweaking to use Scientific Linux repositories. It's also
useless for genuine RHEL releases other than the one you're currently
running, unless you set up local RHEL mirrors, such as setting up
reposync mirrors with all the channels activated..

Also, by default, mock includes the full EPEL repository, and dumps
bulky caches in /var/cache/mock and /var/lib/mock without any
expiration or cleanup. So if you're using mock, be careful to allocate
some significant space for those.
