Subject: netkit-rsh: reproducible-builds: Embedded build paths in binaries

Date: Mon, 26 Sep 2022 14:46:27 -0700

[Message part 1 (text/plain, inline)]

Source: netkit-rsh
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The build path is embedded in various binaries:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/netkit-rsh.html

  /usr/sbin/in.rlogind

  /build/1st/netkit-rsh-0.17/rlogind/network.c
  vs.
  /build/2/netkit-rsh-0.17/2nd/rlogind/network.c

The attached patch to debian/rules fixes this by adding
-ffile-prefix-map to CFLAGS.

Alternately, updating to use dh and a recent debhelper compat version
might also fix this.

According to my local tests, with this patch applied netkit-rsh should
build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining netkit-rsh!

live well,
  vagrant
