The manual ? Articles that get written ? FAQ ?
Also, things we say to help out people in our IRC channel ? You know how
IRC is - it's hard enough to get people to try out stuff and stick to
what you're saying, having yet another hurdle for figuring out what they
should be doing is *really* annoying.

Could definately be added - but the main entry point is still the
unversioned binaries and I've always made sure our docs are in sync with

Please point out these inconsistencies so they can be fixed. Bugs
shouldn't be disguised as features, but fixed.
What is the initial example you mention ?

What broken tools ? Be more explicit please ?

I don't see the complication. It works fine on other platforms. Zaheer
tells me there's no reason why it would be difficult on Gentoo.

What uncertainty is there ? If there are questions, ask them. The
system was put in place precisely to make it more clear.

Since we are the people dealing with these problems, it's really
annoying to have some platform behave differently *just because the
package maintainer can*. I'm saying this with my package maintainer hat
on - I also maintain stuff. If I disagree with some upstream project, I
try to resolve it with that project, and I prefer doing it their way,
not my way - precisely to be more consistent in behaviour over
My personal belief is that a package maintainer should have a *very good
reason* to knowingly work against what the upstream project recommends
or is asking for packages.

"interfere" is a little vague here, isn't it ? I sure hope your
gdk-pixbuf package is registering new capabilities after installing png.

There's a lot of thinking going on :) FWIW, I haven't seen people
complain about how things are packaged on Fedora. Is there really no
way I can convince you to just please follow our recommendations,
realizing that it's just nicer to have things be similar across
systems ? If every package maintainer lets his personal feelings
overrule the project's wishes, it just means that it works differently
on every system. And you still can do what you personally want - just
don't install that tools package.

Another vagary. Are you sure you know the reason why it got introduced,
what it meant to solve ? Are you sure it's repeating these mistakes you
might be thinking of ?
