# Makefile for the different targets used to generate full packages of a kernel
# It uses the generic clean infrastructure of kbuild
# RPM target
# ---------------------------------------------------------------------------
# The rpm target generates two rpm files:
# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
# /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
# The src.rpm files includes all source for the kernel being built
# The <arch>.rpm includes kernel configuration, modules etc.
#
# Process to create the rpm files
# a) clean the kernel
# b) Generate .spec file
# c) Build a tar ball, using symlink to make kernel version
# first entry in the path
# d) and pack the result to a tar.gz file
# e) generate the rpm files, based on kernel.spec
# - Use /. to avoid tar packing just the symlink
# Note that the rpm-pkg target cannot be used with KBUILD_OUTPUT,
# but the binrpm-pkg target can; for some reason O= gets ignored.
# Remove hyphens since they have special meaning in RPM filenames

Description: Linux kernel headers for $version on $debarch
This package provides kernel header files for $version on $debarch
.
This is useful for people who need to build external modules
Package: linux-libc-dev
Section: devel
Provides: linux-kernel-headers
Architecture: $debarch
Description: Linux support headers for userspace development
This package provides userspaces headers from the Linux kernel. These headers
are used by the installed headers for GNU glibc and other system libraries.
Package: $dbg_packagename
Section: debug
Architecture: $debarch
Description: Linux kernel debugging symbols for $version
This package will come in handy if you need to debug the kernel. It provides
all the necessary debug symbols for the kernel and its modules.

%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.
