“pre-inst-env” is a wrapper script that will be created when building
Guix from a git checkout. It ensures that the (possibly modified)
source directory is used for all operations.
If you don’t have a source checkout then you won’t have that script as
you don’t have a need for it.
This discussion is about a change that is not yet part of Guix.
