That would be possible, yes, though we=E2=80=99d have the build-time
dependencies rather than the run-time dependencies (since we cannot know
the run-time dependencies until IceCat is built.)

That said putting all of /gnu/store wouldn=E2=80=99t be that bad I think=E2=
=80=94at
least user data remains inaccessible, which is much better than exposing
/usr on FHS distros.

Thoughts?
