"When it's ready" I guess is the standard answer there. :) it's masked
in ~arch as well, but you can simply unmask it if you want to use it.
That's what I did. I have these sets available in my system currently:
downgrade
installed
live-rebuild
module-rebuild
preserved-rebuild
security
system
unavailable
world
@live-rebuild is especially handy to rebuild live cvs/svn/etc ebuilds
(that -9999 stuff)
