Hmmm...
It would be quite easy to make it so that the kernel version being built for
is not the one running, I think.
The whole "what kernel?" question is resolved in the first few lines of the
revised spec file by the following:
%define krpmvers %(rpm -q --whatprovides kernel | sort | tail -1)
Actually, I got that wrong - it's not the "running kernel" but the "latest
installed version" that gets used.
If this line is changed to the following four:
%define krpmvers_on_cmdline %{?krpmvers:1}%{!?krpmvers:0}
%if !%{krpmvers_on_cmdline}
%define krpmvers %(rpm -q --whatprovides kernel | sort | tail -1)
%endif
Then the kernel to build for can also be specified on the command line, and
should build provided the appropriate sources are available:
rpmbuild -bb \
--target=i386 \
--define "krpmvers kernel-2.4.20-1.1931.2.231.2.11.ent" \
/usr/src/redhat/SPECS/openafs.spec
Then you just need a shell script to go through the list of installed kernels
and build them all:
#!/bin/sh
rpm -q --whatprovides kernel |
sed -e 's/^kernel[a-z-]*-/kernel-/' |
sort -u |
while read krpmvers
do
for cpu in i686 athlon
do
rpmbuild -bb \
--target=$cpu \
--define "krpmvers $krpmvers" \
/usr/src/redhat/SPECS/openafs.spec
done
done
And you only need one set of userspace RPMs and one source RPM:
rpmbuild -ba --target i386 /usr/src/redhat/SPECS/openafs.spec

Our build farm (I think) only runs the latest version of the kernel for any
given distribution.

That's a _lot_ of kernels from where I sit.
