Output a simple RPM spec file.

This version assumes a minimum of RPM 4.0.3.

The only gothic bit here is redefining install_post to avoid

stripping the symbols from files in the kernel which we want

Patched for non-x86 by Opencon (L) 2002 opencon@rio.skydome.net

how we were called determines which rpms we build and how we build them

if [ "$1" = prebuilt ]; then S=DEL else S= fi

if grep -q CONFIG_MODULES=y .config; then M= else M=DEL fi

if grep -q CONFIG_DRM=y .config; then PROVIDES=kernel-drm fi

PROVIDES="$PROVIDES kernel-$KERNELRELEASE" __KERNELRELEASE=$(echo $KERNELRELEASE | sed -e "s/-/_/g") EXCLUDES="$RCS_TAR_IGNORE --exclude=.tmp_versions --exclude=vmlinux
--exclude=.o --exclude=.ko --exclude=*.cmd --exclude=Documentation
--exclude=.config.old --exclude=.missing-syscalls.d"

We can label the here-doc lines for conditional output to the spec file

Labels:

$S: this line is enabled only when building source package

$M: this line is enabled only when CONFIG_MODULES is enabled

Provides: kernel-headers = %{version}
%description headers
Kernel-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs.  The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
glibc package.
