One difficulty with this approach is that search paths are currently a
=E2=80=9Chost-side=E2=80=9D feature: there=E2=80=99s a =E2=80=98search-path=
s=E2=80=99 field in <manifest-entry>,
which is populated before the profile is actually built.

What I suggest above would mean turning search paths into a =E2=80=9Cbuild-=
side=E2=80=9D
feature, which has some implications.

Needs more thought=E2=80=A6
