features:
- In a greenfield deployment containers will now bind mount
all logs to the physical host machine in the
``/openstack/log/{{ inventory_hostname }}`` location. This
change will ensure containers using a block backed file
system (lvm, zfs, bfrfs) do not run into issues with full
file disks due to logging. If this feature is not needed
or desired it can be disabled by setting the option
``default_bind_mount_logs`` to *false*.
upgrade:
- During an upgrade the option ``default_bind_mount_logs`` will
be set to *false*. This will ensure that an existing
deployment is not adversely impacted by container restarts.
If a deployer wishes to enable the default bind mount for
``/var/log`` they can at a later date.
fixes:
- Logging within the container has been bind mounted to the hosts
