When a kernel source tree is installed using ebuilds, Portage tracks and maintains a list of all the files it installs. However, in the process of kernel configuration and compilation, scripts and object code files are created. When these kernel sources are uninstalled with Portage, only the files it placed there originally are removed, leaving the created scripts and object code files in place and thus the directory in /usr/src still remains. I will attach a patch to the kernel-2 eclass which does this automatically using an exported pkg_prerm function.

Created attachment 61476 [details, diff] kernel-eclass-make-mrproper-before-unmerge.patch Adds an exported pkg_prerm function to the kernel-2 eclass to run `make mrproper` in the given kernel source tree directory before unmerging.
I Cant see any problem with doing this. I have updated the eclass here, locally. The prerm function I would prefer to use is: kernel-2_pkg_prerm() { local KV_DIR=${ROOT}/usr/src/linux-${KV_FULL} if [[ ${ETYPE} == sources ]]; then # if we have a config for it then we should act on it. if [[ -f ${KV_DIR}/.config ]]; then cp ${KV_DIR}/.config ${KV_DIR}.config gzip ${KV_DIR}.config fi # have kbuild clean up for us. env -u ARCH make -C ${KV_DIR} mrproper fi } any objections?
make mrproper does not always work (try running it twice) and we should do our usual voodoo for ARCH for cross-compilers
John, Thanks for fixing up the pkg_prerm. That's much nicer. :-) Daniel, I just tried running it twice (after running `make allnoconfig && make` on a gentoo-sources 2.6.11-r11 kernel tree that I've been using to test things, and it failed with an error saying that "/include/linux/version.h" couldn't be found. I've modified John's function to test for that first before running `make mrproper`: ---snip--- kernel-2_pkg_prerm() { local KV_DIR=${ROOT}/usr/src/linux-${KV_FULL} if [[ ${ETYPE} == sources ]]; then # if we have a config for it then we should act on it. if [[ -f ${KV_DIR}/.config ]]; then cp ${KV_DIR}/.config ${KV_DIR}.config gzip ${KV_DIR}.config fi # have kbuild clean up for us. [[ -f ${KV_DIR}/include/linux/version.h ]] && env -u ARCH make -C ${KV_DIR} mrproper fi } ---/snip--- Thanks for the input. What do you mean by "usual voodoo for ARCH for cross-compilers"? Could we simply set what ARCH to use for kbuild based on the current GCC profile?
Look at how tc-arch-kernel is used elsewhere in the eclass
This should probably be done with an USE flag, to prevent .config files and other files to be wiped out without the users's consent.
Im not sure how much the cross-compile stuff has effect here (ie: why I never used it) although to take into account the previous comments please check: kernel-2_pkg_prerm() { local KV_DIR=${ROOT}/usr/src/linux-${KV_FULL} if [[ ${ETYPE} == sources ]]; then # if we have a config for it then we should act on it. if [[ -f ${KV_DIR}/.config ]]; then gzip -c ${KV_DIR}/.config > ${KV_DIR}.config fi # have kbuild clean up for us. if [[ -f ${KV_DIR}/include/linux/version.h ]]; then ARCH=$(tc-arch-kernel) make -C ${KV_DIR} mrproper fi fi } which should solve everyones requirements hopefully. Marcelo, I'm not sure if that would matter, since every kernel is SLOT'ed ${KV_FULL} anyways they would have to explicitly remove it. I asssume if they do so, then they want it gone, completely. However, the .config is backed up for courtesy if it exists. any other comments?
Heh. I was just going to post a similar function. Thanks, John. That Works nicely, here. :-)
comitted to CVS.
Shweet. Thanks very much. :D
