  [Test Plan]

  DEP-8 Tests:

  simpletest - Confirms bind9 daemon starts successfully and dig can
  find 127.0.0.1 through the default setup of bind9

  zonetest - Added in this update, currently in lunar. Confirms the
  functionality of named and bind9 by creating a local DNS zone and
  domain, and having dig look it up

  dyndb-ldap - Verifies functionality of bind-dyndb-ldap against the
  updated bind9 package with a basic setup. This also fails
  intentionally prior to bind-dyndb-ldap being rebuilt against the
  package, as this is a necessary step for bind9 updates.

  validation - This test is provided by Debian and consistently fails
  both before and after the update due to several issues. It is marked
  as flaky, and does not block autopkgtest passing overall

  [Regression Potential]

  Upstream has an extensive build and integration test suite. So
  regressions would likely arise from a change in interaction with
  Ubuntu-specific integrations. Alternatively, regressions may arise for
  users due to behavior changes from the many bug fixes and minor
  feature updates.
