The creation of the log file is necessary to work around a bug in the Debian packaging, that causes the logfile to be created with root as owner, and subsequent causes bird startup to fail because it cannot write to the log file as user bird. :-(
### IP forwarding
For IP forwarding, make sure you uncomment `net.ipv4.ip_forward=1` and `net.ipv6.conf.all.forwarding=1` in sysctl.conf inside the container.

Hint: editing configuration files inside a container can be done from outside the container, by looking for them in the `rootfs` folder inside the container directories.

## Cleanup
Before the birdbase container is ready as a template to be used for cloning other containers, let's remove some container-specific configuration, so we won't accidentally start a new one with duplicate configuration, and, to make the diff look nicer when configuring a clone:
