Thanks for taking an interest in this!

My understanding is that propagated inputs are generally to be used very
sparingly, as they make it very difficult to install multiple packages
that might contain conflicting propagated inputs.

Most of the proposed inputs are largely optional dependencies of
reprotest, which in guix terms, generally the end-user is expected to
install the additional packages to enable desired optional features.

It might make sense to list the additional dependencies in the
description describing what features each enables?

Adding some of them to native-inputs might also make sense to enable
more tests, and give a clear place to write comments about each. Then
"guix shell --pure --development reprotest reprotest" would pull them in
and reprotest itself to be able to run the relevent tests as you had
tried.

If reprotest behaves quite badly without some of the in the working
environment, such as spitting out an ugly backtrace rather than
reporting what is missing, it should probably be fixed upstream (and
possibly patched in guix in the meantime).

It seems like this is missing from the patch, though I suspect it is
needed to behave correctly with things relying on fuse!

Thanks for the detailed report ... this might be or should be covered by
upstream documentation ... although if there are guix-specific angles on
it, I am not sure where that should be documented.


So, in summary, I think there are some ideas to explore from your patch,
although it needs a bit of rethinking about implementation details.
