Various information about the build environment is captured in the

The attached two patches fix this by sanitizing the the files from
debian/rules in the dh_installdocs override and dh_install-arch override
targets.

With these patches applied, gutenprint should build reproducibly on
tests.reproducible-builds.org.


On a somewhat unrelated note, I also noticed needing to override
dh_listmissing to only warn rather than fail on missing various
documentation files. I'm not sure if this was due to something in my
specific environment, or a general issue for the package, but figured it
was worth a heads up.


Thanks for maintaining gutenprint!


live well,
