This works of course. I was hoping to force the dists to stay
in step though. builds are only tagged for el5 and el4 or not at all.
Rather like currently both i386 and x86_64 must both work to get either.
I can force the submitters to build on fc10 as well el4 and 5 to future proof
ourself.

An item relevant to this. When building say a -el4.src.rpm on el5

koji build dist-centos5 foobar-1.5.2.el4.src.rpm

will always fail because the resulting foobar-1.5.2.el5.src.rpm does
not name match  foobar-1.5.2.el4.src.rpm

Is this check useful? It requires one to create to src.rpms before they can
be submitted to dist-centos4 and 5. I can't for instance just grab a
src.rpm package
from fc10 and submit it.

(a cheeky p.s, did you get  the slides I sent. no comment is just fine)
