Fixed that, thanks.

I am explicitly trying to enable users (not just developers) to more 
easily contribute, maintain, and share their own versions of packages.

It does if you're Joe User (or Joe Proxy-Maintainer) and you don't want 
a 1G+ git clone of the whole tree so you can developer 1 package for 
your local repo.

Patchsets suck because you can't just grab a repo and emerge what's in 
it. That's the type of usability we want.

Why don't you check that by running a few commands on profiles/updates/?

Yeah, you tend to get the worst of both worlds here without the full 
benefits of either. If we wanted to split the tree up at this 
intermediate level, we'd probably rather split it into multiple, mainly 
independent dependency trees (e.g. kde, gnome, web-server, system). But 
for that, we'd likely want some way of specifying repository names in

The 10-way forking here on per-arch stable branches would make 
maintenance ridiculous, even if all you have to do is run `git 

Doing this approach right, IMO, means treating an ebuild as stable when 
_any_ of its arches is stable (which I think should be done anyway). How 
I'd do it is that an ebuild in the ~arch tree gets pulled to the stable 
tree (there'd only be 1, shared by all arches) by an arch maintainer and 
_deleted_ from the ~arch tree. Once it hits the stable tree, only arch 
maintainers touch it from that point on. Package maintainers only work 
in the ~arch tree.

Doing it this way avoids the real annoyance of pulling across changes to 
"stable" ebuilds constantly because they aren't actually stable at all, 
they're still under development by the package maintainer.
