0007 # ---------------------------------------------------------------------------
0008 # The rpm target generates two rpm files:
0009 # /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
0010 # /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
0011 # The src.rpm files includes all source for the kernel being built
0012 # The <arch>.rpm includes kernel configuration, modules etc.
0013 #
0014 # Process to create the rpm files
0015 # a) clean the kernel
0016 # b) Generate .spec file
0017 # c) Build a tar ball, using symlink to make kernel version
0018 #    first entry in the path
0019 # d) and pack the result to a tar.gz file
0020 # e) generate the rpm files, based on kernel.spec
0021 # - Use /. to avoid tar packing just the symlink
