Compile vanilla kernels in F17

[Overlord Laharl]

Before Fedora made the decision to create the unified file system in F17, I was able to compile custom vanilla kernels from kernel.org via the following steps:

- download kernel from kernel.org
- untar and move it to /usr/src
- copy an old .config from Fedora's kernel-devel into the new kernel
- make oldconfig
- make menuconfig
- make rpm
- rpm -ivh <new kernel>
- go to /lib/modules/<new kernel>
- change the symlink for /lib/modules/<new kernel>/build to point to /usr/src/rpm/BUILD/<new kernel> instead of /usr/src/<new kernel>
- run mkinitrd and edit grub
- reboot

However, now that F17 has moved with the unified file system, can anyone please explain to me how will this affect a vanilla kernel build since /lib/modules is now located to /usr/lib/modules and what are the precise steps needed to ensure that the kernel installs to /usr/lib/modules and not /lib/modules?

Also, In the future where the /lib and /lib64 symlinks will be removed, how will this affect the vanilla kernel builds again?

Also, how will this affect compat-wireless? compat-wireless always looks into lib/modules/<kernel version> and takes firmware from /lib/firmware , how should I ensure that compat will look for /usr/lib and not /lib or /lib64 in the event that Fedora eventually removes the symlinks?

What's stopping you from creating symlinks?

I'm bumping this thread because I think the OP has some merit-able questions and I'd like to know if anyone has an answer or if there exists (or is in the works) an updated Kernel Compile HowTo.

Hello,
The following should work to the best of my knowledge but has not been tested by me:

Looking through the kernel.spec file for 3.5.3 it appears there are four places one would have to change "/lib/modules" to "/usr/lib/modules".

Hope this helps,
