Right now we pull in the kernel package and the kernel-headers package from different repos and with different versions. i.e. I just spun a build and it says: kernel i586 2.6.17-1.2645.olpc1 olpc_development 4.2 M kernel-headers i386 2.6.18-1.2726.fc6 olpc_rhbase 692 k That's not good. We need to fix it.
I've added kernel-headers to the comps for olpc. The push I started a few minutes ago won't have the change.
