That was dropped _after_ Fedora Core 1 and, subsequently, RHEL 3 --
i.e., it essentially died with kernel 2.4. I explain this and others in
my blog entry here:

Yes is it winded, but I wrote it for a reason. It explains almost
everything you might want to know, as well as "proper" kernel building
which is how Red Hat has been building its own kernels since Red Hat
Linux 6 (yes, that long), that is now their recommended as of Fedora
Core 2 and, subsequently, RHEL 4.

Building the kernel in the system's root has been deprecated ever since
the header issues of Red Hat Linux 7 -- especially once "make mrproper"
was introduced. "make mrproper" cleans out files -- and that means its
better to have it wipe out a /usr/include directory located inside of
the RPM build process chroot than on the actual root of your system.

Again, those procedures are now _useless_ for the most part.
Although Red Hat did include a "kernel-sourcecode-*.i386.rpm" for Fedora
Core 2 for some time, the _default_ in the kernel-2.6.SPEC file since
mid-FC2 is now to _not_ produce that .i386.rpm. anymore. That includes
for RHEL 4.

Rebuilding a kernel is _not_ that much of an issue *IF* you use the same
system that Red Hat has been using since Red Hat Linux 6 -- the same
system forced upon you with FC 2/RHEL 4. Ideally this should still be
in the chroot itself, and _not_ by merely symlinking
from /usr/src/redhat/BUILD/kernel/linux-* to /usr/src/linux-*.
