fixes:
- |
IPV6 is no longer disabled by default in the Ubuntu CIS hardening. If
using the old behaviour you may hit `2071443
<https://bugs.launchpad.net/kolla-ansible/+bug/2071443>`.
upgrade:
- |
To match the new CIS benchmark defaults on Ubuntu, you should remove
the ``ipv6.disable=1`` kernel command line option. If you wish to carry
on with the current settings, change ``ubtu22cis_ipv6_required`` to
``false``.
