+* Docker log-opts are currently not configured in Antelope. You will see these
+  being removed when running a host configure in check+diff mode. See bug for
+  details (fix in progress):

+* /etc/hosts are not templated correctly when running a host configure with
+  ``--limit``. To work around this, run your host configures with
+  ``--skip-tags etc-hosts``. If you do need to change ``/etc/hosts``, for
+  example with any newly-added hosts, run a full host configure afterward with
+  ``--tags etc-hosts``. See bug for details (fix in progress):
