How to file a helpful issue

Qubes OS release

R4.2

Brief summary

CI says core-agent-linux isn't reproducible.

Steps to reproduce

  1. Build core-agent-linux package for Debian bookworm twice
  2. Compare binaries

Expected behavior

Identical binaries

Actual behavior

Sometimes they differ on /usr/share/qubes/xdg-override/mime/mime.cache: https://gitlab.com/QubesOS/qubes-core-agent-linux/-/jobs/6721767136

I think it started happening after merging QubesOS/qubes-core-agent-linux#490, but interestingly enough CI on this PR itself succeeded (including reproducibility test on bookworm).

Current hypothesis: bug in update-mime-database: https://gitlab.freedesktop.org/xdg/shared-mime-info/-/issues/230. I mean, the bug is there, but it isn't clear to me if it's the cause of reproducibility issue.
