[ATrpms-users] How to build rpm for kernel that isn't in repo?

[xyon]

I just grab sources, patch accordingly, configure, save configuration
(also, I make a backup of the config to an alternate dir
(/usr/src/configs)), then do a 'make rpm'. Works like a champ for me,
creates the spec file automatically and so on. If there are problems, I
correct them one by one, but that works 90% of the time OOB.

You could also tar up the directory containing the kernel source and do
rpmbuild -ta on the resulting tar/gz (or bz2) archive. Once you get your
first kernel or two done, it's pretty easy to do further kernels.

I do all this on a build host that handles compiling of packages for
distribution across my infrastructure members, so the kernel is not
automatically installed, it is built and resides
in /usr/src/redhat/RPMS/i386/.

Please let me know if you run into problems and I should be able to help
out.
