Package: zfsutils-udeb Version: 9.2-1 Severity: grave Tags: d-i Justification: renders package unusable Hi, your package is no longer installable, since it gained a dependency on libjail1, which isn't an udeb. This was caught by our edos4udeb script, but that can easily be deduced from the changelog: | - Add libjail-dev to B-D. Debdiffing udeb-producing packages before uploading them would be nice. Mraw, KiBi.
