As Jim pointed out, at this point, it's better:
A) to the "prep" (-bp)
B) change what you want directly in the ./BUILD/kernel-* dir
C) finish off the "build" (-bb)
You don't want to run arbitrary commands in any order. I've seen the
SPEC files _differ_ in command order both before and after the prep.
You should also _avoid_ building on the "root" filesystem. It's best to
stay in the chroot environment.
I've put up my own Blog on this:
http://thebs413.blogspot.com/2005/10/kernel-26-on-fedora-based-systems.html
Select commentary ..
"This addresses many issues, including:
1. Include all components to complete a build
2. Ensure exact steps to complete a build
3. Avoid negative affects to files in the production system (chroot)
4. Force documented changes with source, SPEC, etc...
[ #4 is, of course, optional -- only if you modify the SPEC with
your changes / patch files ]
As of Red Hat Linux 7, I personally and professionally stopped
building kernels from kernel-source[code] ... The exact order and
requirements in not only building but even "prepping" the kernel
source tree for 3rd party kernel modules is extremely important.
But beyond that, the "mrproper" target can do some particularly
nasty things to your systems' /usr/include and other directories.
In the kernel.src.rpm build under the chroot, the
system's /usr/include and other directories are not touched, and
they have their own, self-contained support.
...
That will safely prep the kernel in the RPM chroot environment into
a mode that is "ready to use" under
/usr/src/redhat/BUILD/kernel-2.6*/linux-2.6*/, although you should
consult the kernel-2.6.spec file to see what Makefile targets have
and have not been run. You may wish to create a symbolic linke
to /usr/src/linux-`uname -r` but be careful when executing any
Makefile targets in the unprotected, root filesystem of the
system."
