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