“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. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
