See http://bugs.gentoo.org/show_bug.cgi?id=159876 for some suggestions
for the "test-only-as-root" case. IMO ebuilds should simply test for
the actual capabilities they need in src_test (like uid) instead of
more abstract things like userpriv. If such tests can be used in
several ebuilds an eclass can help to standardize them, but I don't see
a reason to move that logic into the package manager unless those cases
are extremely common.
As for fine-grained user-control, it's a question of quantification as
discussed previously, which isn't easy to solve, or you have to
en-/disable things manually and the issue is part tf the
per-package-env-variables problem (btw, the /etc/portage/env trick only
works because the default src_test in ebuild.sh has the
otherwise redundant FEATURES check which was discussed a few days ago in
one of the commit reviews)
