Where is the kernel source on a Fedora system?

Older systems used to split up the kernel into several packages (kernel, kernel-headers, kernel-source). Fedora kernels are not split up that way. Everything you need to build a kernel module is in /lib/modules/`uname -r`/build. For example, Fedora Core 3 ships with linux-2.6.9-1.667. When configuring PVFS, you would pass -with-kernel=/lib/modules/2.6.9-1.667/build to the configure script. In Fedora Core 4 things changed a little bit. In order to build the pvfs2 kernel module, make sure you have both a kernel and kernel-devel package installed. If you have an SMP box, then you’ll need to install the -smp versions of both – i.e. kernel-smp and kernel-smp-devel. After both packages are installed, /lib/modules/`uname -r`/build will once again contain a correctly configured kernel source tree.
