Subject: cdebootstrap: aid reproducible boostrapping by providing a --cleanup-logs option

Date: Tue, 13 Sep 2022 17:36:40 +0200

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

Package: cdebootstrap
Version: 0.7.8
Severity: wishlist
X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org

Dear Maintainer,

using cdebootstrap 0.7.8 it's possible to reproducible bootstrap Debian,
provided one does three extra steps:

1. rm /var/log/dpkg.log /var/log/alternatives.log /var/log/bootstrap.log /var/log/apt/history.log /var/log/apt/term.log
2. rm /etc/machine-id /var/cache/ldconfig/aux-cache
3. SOURCE_DATE_EPOCH=$some_sane_value ; sudo tar --mtime="@$SOURCE_DATE_EPOCH" --clamp-mtime $SUITE -cf $SUITE.tar

This bug is about the first step. It would be really nice if cdebootstrap
had an option called --cleanup-logs which would delete those logs.

Step 2 (or rather it's first part) is tracked via #1018741: "cdebootstrap:
better initialisation of /etc/machine-id".
Step 3 would be another new feature for cdebootstrap, namely to create tar archives.

Thanks for maintaining cdebootstrap!

Would it be sensible to suggest that, instead of an explicit
command-line flag, that debootstrap would do this cleanup if
SOURCE_DATE_EPOCH is present?

If it helps, the idea of using the presence (or non-presence) of
SOURCE_DATE_EPOCH to slightly adjust the behaviour of a program is
already being used as a flag in other places.

(If it helps, the parallel bug for debootstrap is #1019697.)

I think that's an excellent idea! :)
