Description aabarkley3 2014-12-16 16:08:08 UTC

+++ This bug was initially created as a clone of Bug #424816 +++

This bug follows a recent discussion on @gentoo-dev wrt. building kernel as non-root.

/usr/src/linux is sys-kernel/hardened-sources-3.2.11, whereas /usr/src/linux-main (owned by non-root) is the result of "make -C /usr/src/linux O=/usr/src/linux-main modules_prepare". /etc/make.conf contains "KBUILD_OUTPUT=/usr/src/linux-main".

# grep 'declare.*/usr/src/linux' /var/tmp/portage/app-emulation/virtualbox-guest-additions-4.1.12/temp/environment 
declare -- BUILD_PARAMS="KERN_DIR=/usr/src/linux KERNOUT=/usr/src/linux-main"
declare -x KBUILD_OUTPUT="/usr/src/linux-main"
declare -- KERNEL_DIR="/usr/src/linux"
declare -- KERNEL_MAKEFILE="/usr/src/linux/Makefile"
declare -- KV_DIR="/usr/src/linux"
declare -- KV_OUT_DIR="/usr/src/linux-main"
declare -- OUTPUT_DIR="/usr/src/linux-main"
