This command line : $> ~/devel/tip $ sudo su -c "mount /boot; genkernel --makeopts=-j4 --kerneldir=`pwd` --no-install kernel ramdisk" installs the modules in /lib/modules/3.11.0+ for the given kernel version) Background : I'd like to control this step with a separate "make modules_install" For bisecting I do not want pollute /boot with so many different files therefore I'm using currently this command sequence for bisecting a kernel bug: ~/devel/tip $ sudo su -c "mount /boot; cp /usr/src/linux-3.13.x/.config . && genkernel --clean --makeopts=-j4 --kerneldir=`pwd` kernel initramfs && cp arch/i386/boot/bzImage /boot/test && rm -rf /lib/modules/3.1?.0?* && make modules_install && mv /var/tmp/genkernel/initramfs* /boot/initramfs-test && sleep 6 && reboot" and jutst pointed grub2 to "test" as the default menu item.

@bkohler: Your solution introduced a breakage (both in it's original form and my equivilent patch) Specifically, if you pass: --no-install but want to create packages instead via --modulespackage/--minkernpackage, then it's not installed at all, and it can't create a modulepackage: * Creating modules package * Could not create a modules package /var/tmp/portage/sys-kernel/gentoo-infra-kernel-sources-4.14.8-r1/temp/lib/modules/4.14.8-gentoo-r1-infra37 was not found I'm wondering if we need to seperate out the module install, and do a seperate tmpdir install for the package, and then if install is enabled, rsync from the tmpdir to final.
Been looking at this issue this morning. These installed modules in /lib/modules/ are used by kerncache, minkernpackage, and modulespackage (if there are any more, please let me know). Where right now in compile_modules() we have recently added a simple "return" for NO_INSTALL, instead we should detect if any of those 3 features is set, and do an extra "make modules_install" with INSTALL_MOD_PATH="${TEMP}/no-install" set. Then return. Right now in those 3 functions using /lib/modules, we already have checks to use ${INSTALL_MOD_PATH}/lib/modules if it exists, we can add another check to use ${TEMP}/no-install/lib/modules if it exists. Thoughts? Trying to get this done with minimal changes to the existing code.
