In regards to bug #85012 I'm just wondering if something needs to be done with the "kernel-mod_configoption_present" function available from within all ebuilds. Currently it checks /usr/src/linux/.config for a particular kernel configuration option but this is not compatible with the new KBUILD system. One new method of checking could be to: 1) First check /proc/config.gz 2) Then "${KBUILD_OUTPUT}"/.config should be checked if the above kernel feature hasn't been enabled. This will probably continue to plague ebuilds using the function until a new approach is taken.
kernel-mod has been deprecated, and linux-mod should be used. This is resolved in this new eclass.
