Real kernel compilation for fedora

[markg85]

Hey,

Falko has written this document: http://www.howtoforge.com/kernel_compilation_fedora
and i really like it but it's not the real fedora way.
with that documentation you still have to manually edit grub and you still have to do mkinitrd. So my request is a new document that does it exactly the fedora way so that you end with a kernel rpm that does the grub and mkinitrd for you.

i think it would be best to edit that document with something like: go to page # for manual stuff (mkinitrd, grub) or go to page # to create a kernel rpm (with mkinitrd and grub in it).

Mark.

Do you have some instructions how this works?

actually i have just got it from a reply on the fedora-devel-list.

Here is sopme official documentation but i find that incomplete:
http://docs.fedoraproject.org/releas...sn-Kernel.html

The thing that one reply suggests is doing:

It depends on what you want to do. Your question seemed to be: How do I
get "rpmbuild -ba kernel-2.6.spec" to produce kernel rpms. The answer
is:
rpmbuild -ba --target $(uname -m) kernel-2.6.spec

I should have made it clearer in my original reply that the
"--target...." was the only thing you needed to get from that page.

If you want to make modifications to the kernel spec file, then the rest
of that page becomes relevant.

where "that page" is your howto for the kernel compilation.

I think the best thing you can do is extract the rpm, than extract the kernel source than edit the kernel to your own wishes (make menuconfig) than save it and make the compressed archive again. than you can do:

rpmbuild -ba --target $(uname -m) kernel-2.6.spec

to make the kernel but be aware that some patches might overwrite your changes.
hope this helps

So if I understand you right, instead of

rpmbuild -bp --target=i686 kernel-2.6.spec

I'd run

rpmbuild -ba --target=i686 kernel-2.6.spec

and wouldn't have to worry about the Ramdisk and GRUB anymore? Is that the only difference?

[markg85]

Sorry for the late reply.

Yes. if you do that than you don't have to worry about that ramdisk and grub. Compiling has to be done either way so better do it that way saves you time for when you want to install the kernel.
