Just installed texlive-bibexport, which is a bash script used with .aux files in a LaTeX project to create project-local BibTeX files, and found that it has a hard-coded shebang of:

`#!/bin/bash`

This is not a problem if the system has a /bin/bash, but the default in GNU Guix is still currently not to, and therefore this script should be patched to use the following, or similar:

`#$(file-append bash "/bin/bash")`

This would allow it to function without requiring the creation of a literal `/bin/bash`.

Thoughts?
