This bug is for feedback and bug reporting on EAPI=4-slot-abi testing , as provided by the portage tree fork found in my developer overlay:

http://git.overlays.gentoo.org/gitweb/?p=dev/axs.git

OVERLAY USAGE:

0 - check the website to make sure my overlay is not too out-of-date compared to your copy of the tree.  I am trying to keep the overlay in sync within 24h of CVS HEAD, but it is difficult as only part of the upgrade can be automated.

1 - emerge =sys-apps/portage-9999 to obtain a copy of portage supporting EAPI=4-slot-abi

2 - obtain a copy of my overlay (layman -f ; layman -a axs)

3a - gradually upgrade your system, replacing packages from portage with the overlay's EAPI=4-slot-abi equivalent versions.  Alternatively, emerge -e @world to replace 'em all.

3b - instead of re-emerging, use my portage-vdb hack to simulate the re-emerging of all installed EAPI=4 packages to their overlay equivalents.  This is what I do, but be warned that this is not something to be taken lightly (unless you're on a disposable image like a chroot) and may cause severe breakage of portage.  

3b.1 - unless you feel very lucky, make a backup of /var/db/pkg
3b.2 - run /var/lib/layman/axs/hack-4slotabi-into-portagedb.sh, watch for errors in the output or anything that seems particularly odd.
3b.3 - run emerge -uDp @world to check if it worked and all seems OK.
3b.4 - DO NOT emerge anything until you are sure that the vdb is OK.  If in any doubt, restore the backup.

EAPI5 has been enabled for in-tree ebuilds for a few months now, closing the bug. 

I've also not updated my overlay for a few months so I'm going to drop the ebuilds.
