Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or becoming root oneself or it errors out. Unless already running as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a good default. With this patch applied, you can run "make oldconfig deb-pkg" as an ordinary user to build a binary package for an updated kernel tree and it should just work. fakeroot is too zealous by default in treating files as owned by root. Its wrapped stat() sets st_uid and st_gid to 0 for all files, which causes Git to go on a wild goose chase if CONFIG_LOCALVERSION_AUTO is set, checking if any file's content has changed along with its stat information. Avoid this by telling fakeroot to use the actual owner and group for preexisting files, by passing it the -u option.

# Makefile for the different targets used to generate full packages of a kernel
|
|
# It uses the generic clean infrastructure of kbuild
|
|
|
|
# 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.
|
|
|
|
# Do we have rpmbuild, otherwise fall back to the older rpm
|
|
