   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.
