+# Currently the pulp_deb plugin in Pulp does not support certain types of
+# content, including i18n files and command-not-found indices. This breaks APT
+# when the command-not-found is installed. This playbook can be used to
+# uninstall the package, prior to running any other APT commands. It may be
+# installed as a hook to the 'host configure' commands.
+# See https://github.com/pulp/pulp_deb/issues/419
+# FIXME: If used as a hook, this playbook matches all hosts, so will run
+# against the seed, even when running 'overcloud host configure'. Depending on
+# the stage of deployment, some hosts may be unreachable. This could be fixed
+# by implementing this playbook separately for each group.
