Automating build of stable kernel release candidates
There are some manual hacks in the kernel specfile now for building
stable release candidates. However, kernel 2.6.23.9-rc1 ends up being
released as 2.6.23.8-NN because we don't have a good way to change the
version. This update automates that; the only question is whether we
should label the built kernel as an -rc. I didn't add that part, and the
changes are untested:
--- kernel.spec 29 Nov 2007 00:25:06 -0000 1.279
+++ kernel.spec 29 Nov 2007 22:45:41 -0000
