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.
12 # Process to create the rpm files
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
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.
