features:
- In a greenfield deployment containers will now bind link
their journals to the physical host machine in the
``/var/log/journal/{{ machine_id }}`` location. During an
upgrade this change will be added to the container config but
will not go into effect until the container is restarted.
Because the restart is not forced the operator can perform
restarts to best suit the needs of their environment.
Journal linking provides operators the ability to log stream
and health check containerized systems without having to
attach or otherwise login. If this feature is not needed or
desired it can be disabled by setting the option
``lxc_container_journal_link`` to *false*.
