I sounds like the shebang is actually longer than Linux=E2=80=99s static li=
mit.

Indeed, the string
=E2=80=9C/tmp/packerbuild-1000/guix-git/guix-git/src/guix/test-tmp/store/wz=
k9i3vyr53xiyxl6ar7ykyifxhfxqpv-bootstrap-binaries-0/bin/bash=E2=80=9D
is exactly 126 characters, but BINPRM_BUF_SIZE in Linux, which accounts
for the entire shebang plus trailing zero, is 128.

Commit b69c5c2 works around that by skipping tests that would otherwise
hit this limit.

I will also add configure-time checks to at least warn about the risk of
such problems.

Thanks for the report!
