Hi,

using the method described in
http://crab-lab.zool.ohiou.edu/kevin/kernel-compilation-tutorial-en/steps.html
to build customized kernels from FC3' kernel src.rpms, I faced
unexpected problems with 2.6.11-1.14_FC3. So I downloaded, configured,
compiled and installed the vanilla kernel 2.6.11.7 instead. Works like a
charm. Unfortunately, the huge kernel build directory (over 400MB
before, 231MB after "make clean") occupies really a lot of HDD space. It
contains - what else - the complete kernel source while the directory
/lib/modules/`uname -r`/build of Fedora's own kernel RPMs contains only
headers and makefiles.

Is it safe to free the disc space and to delete everything in the kernel
build tree except of headers, makefiles and Kconfig files? (I would like
still to be able to build applications and external modules from source
when needed.) Is there a command to do it automatically?

I'm sorry if the question is naive; my Linux experience is still very
limited.

Thanks i.a.,

Ilja
