If you want to change the set of modules enabled you'll have to do a bit more as the kernel .config options aren't exposed in the spec file in a way that you can control via rpmbuild options. That said, you should check out Richard's suggestion as you may find that it's the many variant (up/smp/pae/debug/debuginfo etc.) sub-packages that are chewing up the time for you. If turning those off gives you an acceptable build time it's less invasive than munging the KConfig options to drop unneeded modules. If you decide you do need to do that though you'll need to install the SRPM (either with bare RPM build directory or via mock) so that you can get access to the individual sources and patches that make it up. If you're using the normal RPM directory layout then the files you're interested in will end up in $rpmbuild/SOURCES (where $rpmbuild is whatever RPM's %_topdir macro is set to). For the kernel the interesting files are config-*-generic, config-*-smp etc., Makefile.config and a perl script named merge.pl: $ cd rpmbuild/SOURCES $ ls config-* merge.pl Makefile.config config-arm-generic config-powerpc32-generic config-arm-highbank config-powerpc32-smp config-arm-imx config-powerpc64 config-arm-kirkwood config-powerpc-generic config-arm-omap-generic config-rhel-generic config-arm-tegra config-s390x config-debug config-sparc64-generic config-generic config-x86-32-generic config-i686-PAE config-x86_64-generic config-local config-x86-generic config-nodebug merge.pl Makefile.config The structure of the config files is fairly self-explanatory; config-generic is the global catch-all and architectures and variants (e.g. PAE, smp) can override specific values as needed. If you just want to make a few local changes you can drop them into config-local - this should have the highest precedence and is is automatically merged by kernel.spec during %prep.
