I can't see any great advantage of this new structure, and indeed I
think it will lead to more chaos and anarchy than there is already.

I think the idea with this was of "freezing" the tree, and then only
adding bugfixes to the frozen tree to provide enterprise level QA.

I think you'd struggle to get Gentoo to stop being on the bleeding edge :)

Don't these relate more to the packages we provide than our structure?

We could of course move in several directions at once...

Don't we already provide most of these tools?

How does this proposal help to bring us forward in this respect?

I'm not convinced of this distinction. While many people cite the
interactions on the forums, mailing lists or bugzilla as evidence of
it, if you look at IRC I think you see a quite different picture. I
know several users who I get on well with, and who participate

Just because people want freedom doesn't mean they won't abuse it.

I don't think this is a good idea. Most projects are short on people
already, without having to have their members wasting time policing
themselves.

People can already do this anyway, they just need to put up a tarball
and pop into #gentoo-overlays and ask it be added to the overlay list
for layman.

This is hardly a good example. Pkgcore and paludis both have totally
different codebases to portage, heck, paludis is written in a
different language. What you talk about above is different _ebuilds_,
and I have yet to see a serious dispute over ebuilds that has not been
settled in tree. The only existing ones I can think of are new
unstable or live ebuilds for packages that the maintainer will not
accept.

I think this is the least of your worries.

The extended atom syntax allows a repo-id to be included in the atom,
in the form category/package::repo (versions, slots etc can be
included too). You could have kde-base/kde::kde for the kde package
from the kde repo for example. This would at least make this proposal
slightly less chaotic were it actually to take place.

Who would put in this information? Wouldn't it be easier to fix the QA
problems rather than listing them? Unless the ebuilds are in a
different overlay, oh wait they are(!). This is a problem with the
whole "lets split the tree up into overlays" idea. People act as
though devs being allowed to commit to the whole tree is a bad idea. I
have seen several mails expressing this, and talked to several people
on IRC who were shocked when they realised this. Why? The whole point
of being given commit access is that Gentoo is trusting that person to
commit to the tree, and if they are not trusted enough to commit to
the whole tree they should not have been given access in the first
place.

Another format?

This hardly seems to offset the negative effects.

Not at all. Just because projects would be tiered does not mean they
would naturally lend themselves to a distributed scm, they would in
effect just be overlays. See the scm topic for more discussion on
this.

Just because stuff isn't maintained doesn't mean that it's not being
used, and if it's not broken I fail to see why it should be removed.

This demonstrates how badly the idea of splitting the tree into
multiple overlays scales imo. Unless you give arch teams access to all
repos. But what about the recent kde vs. mips incident? What if the
kde team decided to disallow the mips team access to their repo? Who
looses out in the end? Users.

/me would strongly disagree

While I like and respect you, I can say with my hand on my heart, I
hope this proposal is never implemented.
