Right.

Agreed, the plan makes sense and I think we have all the bits.
A related question is whether to encode search path environment
variables into the manifest (currently they are “guessed” by looking at
same-named packages; see (guix build package).) I think that would
probably simplify things and make it easier to share this environment
variable code.
Thoughts?
Thanks,
