Kernel development on Fedora

[W. Michael Petullo]

I am interested in doing some kernel development on Fedora. I am familiar
with kernel internals, but I am looking for some tips to help manage the
build, compile, and install cycle. Unfortunately, I am developing against
the Linux Security Module interface, so my work cannot take the form of
a kernel module.

I would like to build RPMs because they are convenient to install,
and they manage the kernel configuration for me. Put another way, I
would like for practical reasons to track the Fedora kernel source RPMs
as opposed to the upstream kernel tree. (This will eventually change,
but not yet.)  However, building RPMs results in a full build each time,
slowing down the development cycle.

I thought that I could speed this up using rpmbuild's --short-circuit.
My idea was to perform an "rpmbuild -bp" once, apply my own changes to
the build tree, and then on each compile run "rpmbuild -bc", "-bi", and
"-bb".  The problem is that the RPM build runs "make mrproper" as part
of the %build target.

Does anyone know of a good work flow for developing custom kernel code
on Fedora in a convenient way? The next best thing I could come up with
is to recreate much of the kernel RPM's %build target without the "make
mrproper" and other troublesome parts. But this sort of duplicates things
that I would rather dynamically track by making use of each kernel RPM.

Thank you,
