OpenStack-Ansible sets a new variable, `galera_disable_privatedevices`,
that controls whether the `PrivateDevices` configuration in MariaDB's
systemd unit file is enabled.
If the `galera_server` role is deployed on a bare metal host, the MariaDB
default is maintained (`PrivateDevices=true`). If the `galera_server` role
is deployed within a container, the `PrivateDevices` configuration is set
to `true` to work around a systemd bug with a bind mounted `/dev/ptmx`.
See `Launchpad Bug 1697531 <https://bugs.launchpad.net/openstack-ansible/+bug/1697531>`_
for more details.
