Bugzilla Bug 167277

Some notes on ROOT:

* The idea behind ROOT is that one can build a system with ROOT=/somewhere and
then chroot into it or tar up /somewhere as a system image. It is not designed
to allow the user to run /somewhere/usr/bin/foo.

* ROOT can't be used correctly in src_*, since ROOT might be different when
merging a binary package. For example, a binary package might be built with
ROOT=/ and then installed onto a system using ROOT=/somewhere.

* ROOT isn't used for library dependencies. When building, libraries, headers
etc. on / have to be used. Cross-compiling etc is done by configuring the
toolchain correctly, not by hacking ebuilds in a way that breaks binary
packages.

KDE done already.

games done

So, gnome-games uses ${ROOT} to access the live filesystem to see if scorefiles
already exist, and if so, doesn't overwrite them.  What is the correct way to
do this?

the same way we do it in games.eclass ... pkg_preinst

Thanks for the pointer; the eclass was doing better.  Gnome fixed.
