Is there any particular reason to go this route?

Writing portable scripts is full of all sorts of pitfalls and ill-meaning
dragons:

- What if SHELL=tcsh?
- What about incompatible behaviour between bash versions?
- Do we want to write tests to future-proof fixes for the above?

In this case, since the build is running inside a guix shell, I don't really
see any reason to *not* effectively pin the scripts to use the bash available
in that environment.

Am I missing something?

Cheers,
B
