[gentoo-dev] G/FBSD compatibility: root:root and cp -a

Ok, to help devels know which are the requisites of Gentoo/FreeBSD porting (as 
we're going near to a release, I hope), I think it's better telling here what 
we hope you all will avoid (and we must replace when keywording).
Those problems are also valid for ppc-macos AFAIK, so you won't help just us, 
but also ppc-macos project.

The first one is the root:root problem (there's no root group in *BSD and 
BSD-based systems); the solution is usually using 0:0 to chown. If nobody is 
going to disagrees with this, I think this solution is what we should use.

The other problem is with cp -a: -a is a GNU option which is not supported by 
non-GNU cp commands. As the man pages says, it's equivalent to -dpPR. 
Unfortuately -dpPR is not portable in itself, but usually what you need is 
-pPR which works just fine usually.

I'm not going to have a big immediate change of all the ebuilds in portage, 
but at least I hope new ebuilds doesn't get added with those problems in 
them :)

HTH,
