1# Makefile for the different targets used to generate full packages of a kernel
2# It uses the generic clean infrastructure of kbuild
3
4# RPM target
5# ---------------------------------------------------------------------------
6# The rpm target generates two rpm files:
7# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
8# /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
9# The src.rpm files includes all source for the kernel being built
10# The <arch>.rpm includes kernel configuration, modules etc.
11#
12# Process to create the rpm files
13# a) clean the kernel
14# b) Generate .spec file
15# c) Build a tar ball, using symlink to make kernel version
16#    first entry in the path
17# d) and pack the result to a tar.gz file
18# e) generate the rpm files, based on kernel.spec
19# - Use /. to avoid tar packing just the symlink
20
21# Note that the rpm-pkg target cannot be used with KBUILD_OUTPUT,
22# but the binrpm-pkg target can; for some reason O= gets ignored.
