Clean up catalog journal

From bind-users

Hi

Using BIND-9.16.19: When removing a member zone from a catz (catalog zone), then the journal files are not removed on the slave:

Current situation before removing the zone "example.com" from catz:

$ ls -lahF
-rw-r--r--. 1 named named 4.0K 28. Jul 15:21 __catz___default_catalog.123456.local_example.com.db
-rw-r--r--. 1 named named 1.2K 28. Jul 15:26 __catz___default_catalog.123456.local_example.com.db.jnl


After removing the zone on the master (catz), the slave removes the __catz___default_...-files for the corresponding zone, but not the journal-file:

28-Jul-2021 15:29:56.018 general: info: catz: updating catalog zone 'catalog.123456.local' with serial 2021072803

$ ls -lahF
-rw-r--r--. 1 named named 1.2K 28. Jul 15:26 __catz___default_catalog.123456.local_example.com.db.jnl

Is this intentional or possibly a bug?

Many thanks.
Kind regards,
Tom
