kernel/scripts/package/Makefile

   1 # Makefile for the different targets used to generate full packages of a kernel
   2 # It uses the generic clean infrastructure of kbuild

   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.
