[gentoo-user] repos.conf migration lost overlay priority

[Nikos Chantziaras]

I migrated my portage config to the new repos.conf system. I now have a 
file /etc/portage/repos.conf/local.conf:

   [Local]
   location = /usr/local/portage
   auto-sync = no

And removed the path from make.conf.

However, now layman overlays override my local repo. If I copy an ebuild 
to /usr/local/portage (for modifications) and try to emerge it, it is 
not emerged. Instead, the ebuild from the other overlay is emerged.

How do I make my local overlay have the highest priority so that it 
overrides *everything*?
