[gentoo-proxy-maint] debugging an FHS issue

[Vieri]

Hi,

When an emerge shows this kind of message:

 * The ebuild is installing to one or more unexpected paths:
* 
*  /run
* 
* Please fix the ebuild to use correct FHS/Gentoo policy paths.

can I make emerge be more verbose as to "what" the ebuild is actually trying to do?
It can be anything within the ebuild (in which case it should be easy to spot), or something resulting from an "emake install" (which of course is a whole different ball game).

For instance, if an ebuild contained the following code within src_install:

rm -rf "${D}"/run/app

would it yield the aforementioned warning?

Thanks,

Vieri
