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.
