Great :)

Ohh, I forgot -- we currently use something like

ExclusiveArch: i586, i686, x86_64, ppc

to specify the target archs to build for. Some people don't like that --
it would be good if the buildsys could handle this, too (but of course
the buildsys should not try to build for i386 -- that will fail).

yes, glibc and some other ppc64 packages where 64 bit might be an
advantage.

Yeah, I know. For ppc-build that's okay and the best solution, but to
build ppc64 kmod's we need to include at least kernel-devel*.ppc64 and
probably some other crucial packages, too (glibc.ppc64 libgcc.ppc64 ?
maybe others ).

I tried to build a kmod for ppc64 with mock once -- worked just fine
after removing the 
Exclude = *.ppc64
from the mock-conf for the target and putting
ppc64-redhat-linux
into /etc/rpm/platform on the host. So it shouldn't be a big deal to set
a plague-builder up for ppc64 somewhere. But how to we make sure that
only kmod's are build for ppc64 (and not everything). Can plague handle
that?
