+  ## Since `base` has a dependency for docker it would install and start the daemon
+  ## without the docker daemon config file generated by `net`.
+  ## This means that the docker daemon will create a bridge and install iptables rules
+  ## upon first startup (the first time this playbook runs on a specific host).
+  ## Since it is a tedious task to remove the interface and the firewall rules it is much
+  ## easier to just run `net` before `base` as `net` does not need anything from `base`.
