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