Bug 430213

Description of problem:

koji-1.2.2-2.fc8
mock-0.8.19-1.fc8

I'm sort of lost with working through this one.
this is an issue in the interaction of koji and mock that I've been tearing my
hair out over. So feel free to toss this over to the koji folk if you feel it
doesn't fit here.

koji generates the mock config to be used in /etc/mock/koji/ so this is not
something I truly have control over 8/

when mock fires up it gets as far as running
/usr/sbin/groupadd -g 0 mockbuild
but dies since 0 is already assigned

now I hand built a much more simple mock cfg file to do the same as above and it
happily uses a non 0 GID
DEBUG util.py:239:  run cmd timeout(0): /usr/sbin/groupadd -g 490 mockbuild
But I can't determine for what reason the koji generated version assigns 0

BUT this all aside, would the solution be to to edit
/usr/lib/python2.5/site-packages/mock/backend.py :505 to allow mock to run
groupadd with the -o flag ? or is this just a terrible cowardly way of hiding a
configuration problem?
