Bug#990338: autogen: reproducible-builds: embeds /bin/sh or /bin/bash in autoopts-config

[Vagrant Cascadian]

Source: autogen
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: shell
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

Depending on what /bin/sh symlinks to, either /bin/sh or /bin/bash is
embedded in autoopts-config:

  https://tests.reproducible-builds.org/debian/rb-pkg/experimental/amd64/diffoscope-results/autogen.html

  ./usr/bin/autoopts-config

  #!·/bin/bash
  vs.
  #!·/bin/sh

The attached patch fixes this by hard-coding CONFIG_SHELL=/bin/sh in
configure.ac.

I tried passing to configure or setting it in the environment, but both
approaches were ineffective.


Applying this patch *should* make autogen build reproducibly.


Thanks for maintaining autogen!


live well,
