sudo layman -S; sudo emerge --sync
I get this message:
The source of the overlay "einit" seems to have changed. You currently sync from "http://einit.svn.sourceforge.net/svnroot/einit/trunk/distro/gentoo/portdir_overlay" while the global layman list reports "http://svn.berlios.de/svnroot/repos/einit/trunk/distro/gentoo/portdir_overlay" as correct location. Please consider removing and readding the overlay!
... and I can't work out how to do this - which file to edit?
