Set PrivateDevices=false for Galera
This patch sets the `galera_disable_privatedevices` variable in the galera_server role. If galera is deployed with a container, the PrivateDevices configuration will be disabled in MariaDB's systemd unit file. Related-Bug: 1697531 Change-Id: I3dce66a5fa94d8a1a27280244622ca68036e6ad1

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>`_
