ci: diff back-to-back built images
Only known differences are accepted. Useful for finding new, unexpected differences.
The current list of accepted differences is a start; IMO we should shrink it.
This is probably considered blocked by:
- https://github.com/grml/grml-debootstrap/issues/252
But I think it should not be considered blocked because of that. I think this PR would be good to be merged rather sooner than later to avoid merge conflicts. It seems to be a nice feature towards reproducible builds.
While the actual test is still broken on CI, it's still adding informative output to grml-debootstrap. I might even send a PR to improve that debug output. Also any scripts to diff two different VM images are nice for local use.
As long as https://github.com/grml/grml-debootstrap/issues/252 is pending, simply keep the test disabled on CI so CI does not break until this gets fixed in the future?
simply keep the test disabled on CI
we can just keep the PR open, no?
