Bug#1009797: apt: support "nodoc" build profile

[Vagrant Cascadian]

Source: apt
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

There are some non-deterministic identifiers that doxygen introduces
into apt's documentation packages:

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

The attached patch, adds support for the "nodoc" build profile, allowing
to build the other apt packages reproducibly by excluding the
documentation packages.

This also allows building functional apt packages with a smaller
dependency chain, so might help with bootstrapping efforts too!

I thought docbook* and xsltproc could also be excluded from the
Build-Depends, but that triggered some other build failures.


Of course, ideally building documentation reproducibly would be very
nice as well, so it would be good to eventually fix the underlying
issues in doxygen:

  https://tests.reproducible-builds.org/debian/issues/unstable/nondeterministic_ordering_in_documentation_generated_by_doxygen_issue.html


Thanks for maintaining apt!


live well,
