Hi,

independent from my last question, I would like to try to compile
patched kernel packages. What is the best way to build them efficiently?

Following the Howto I found
(http://www.xadux.eu/wiki/1107-kernel-bau-aus-den-kernel-source-src-red-hat-package-manager.html;
in german) I need to go through the following steps:

1. Install the kernel source src.rpm
2. patch-what-you-need, set new version number
3. copy kernel-defaults.spec and kernel-syms.spec to SPECS
4. rpmbuild -ba kernel-source.spec
   rpmbuild -ba kernel-default.spec
5. install kernel and reboot with the new kernel
6. rpmbuild -ba kernel-syms.spec

I have now three problems here:

1. Spec files for kernel and symbols
====================================

The kernel source src.rpm does not contain kernel-default.spec and
kernel-syms.spec, but rather kernel-binary.spec.in  and
kernel-syms.spec.in. How can I generate the spec files from them?

2. Patching the kernel
======================

To patch the source, I added a mypatch.tar.bz2 to the SOURCES dir, in
kernel-source.spec appended a line

Source300: mypatch.tar.bz2

at the end of the sources list, added a "-n 300" in the "%setup" line.
In series.conf, I added the lines

########################################################
# Local patches
########################################################
        patches.me9x00/me9x00.patch

This compiles already quite well :-) However, I also want to change the
kernel .config (increase the max and runtime number of UARTS). What
would be the best way to do so? What I did is to write a diff to
config.tar.bz2 and put additional lines in kernel-source.spec:

Patch: increase_nr_of_uarts.patch   (after the "Source300" line)

%patch                              (after the "%setup" line)

Are there any drawbacks with that or is this the recommended way?

3. Version number
=================

I changed the "Release" line of kernel-source.spec to

Release:        0.2.1.mycompany.1

Does this sound reasonable or is there a recommendation for private
numbering?

Best regards

Ole
