T-shooting Tips for a Failing Mock-init (code: QWERTY)

[Tweeks]

Hey all,

I probably banged my head with some of your in the #koji channel a  couple of weeks ago on this.. but I never got it figured out.  My work group was trying to set 
up a CI/CD Jenkings test & build server using Jenkins + Koji (all on one box) and ran into some probelms.  Besides the documentation not exactly being well suited 
for SSL auth configs, we found that we could get everything working except the actual mock portion.  The mock chroot seems to get mostly set up (packages installed 
by kojibuilder/kojid), but when the system tried to do the mock-init, it fails every time.

We even tried following the #koji guys' suggestions of invoking mock manually from the command line like this:
=============
# su - kojibuilder
-bash-3.2$ mock -r koji/dist-c5-build-6-10 --init

^^^^^^^^^^^^^^^

Anyone have some good t-shooting tips?
BTW.. I'm just trying to build a RHEL zsh src RPM here. nothing fancy.

Our system is CentOS 5.8 (a requirement), koji-1.7.
