my repo uri: http://github.com/TommyD/gentoo-portage-multilib
This is the cleanest I could get out of the easy approach you agreed to: http://git.goodpoint.de/?p=portage.git;a=shortlog;h=refs/heads/multilib Wasn't as easy as it looks. This is what I propose to run on your end: # git clone --origin goodpoint git://git.goodpoint.de/portage.git # cd portage # git checkout -b multilib goodpoint/multilib # git remote rm goodpoint And then # git remote add overlays-gentoo-org git://git.overlays.gentoo.org/proj/portage.git # git fetch overlays-gentoo-org # git merge overlays-gentoo-org/master ... Btw I have verified the result of my conversion using # diff -rq --exclude=.git portage gentoo-portage-multilib Please let me know how this works out for you.
