[gentoo-user] removing an overlay

Hello,

I've just sync'd my machine, and realized I'm pulling in a few packages from
the devnull overlay that I would rather not. freetype / fontconfig / cairo
for example and it's causing
some conflicts when I try to update (-auvND world). I mainly use devnull for
uzbl, dmenu, and my window manger awesome, as they tend to have the latest
versions.

If I remove devnull, will these packages continue being maintained by
portage? I don't mind getting these packages from portage if it means less
hassle when I update, but the docs
suggest that I remove every package that I've installed from devnull before
moving forward. This seems like a tremendous hassle, but perhaps there's a
one-shot command for doing this?

I'm surprised packages in overlays take precedence over portage. Is there
any way to get a single package from an overlay without taking "everything"
?

Kind regards,
-Alan

There's no one-shot command because it's a series of actions.

layman - devnull
emerge -av1 <list of stuff from devnull>

portage won't nuke your packages just because you remove the overlay, it still 
has the ebuild locally. portage will only update them once the version in 
portage is greater than the version you got from the overlay.

emerge -pv @installed will then show packages you do not have ebuilds for 
(amongst other useful info) with portage-2.2*. You can then decide what you 
want to do about those missing packages.

An overlay has to take precedence, otherwise putting a fixed ebuild in
your local overlay will have no effect.

What I do it ad the overlay with layman, so it is kept up to date, but
don't add it to make.conf. Then I symlink the packages I want from that
overlay to my local overlay.

You are about to give someone a piece of your mind,
something you can ill afford...
