Hello Alexander,

please find my remarks inline below.

Here, the tcp_terminal is nagging about a missing policy configuration
for a client  session request labeled 'vfs -> '. Thus, it may be good
to provide one in the <config> of tcp_terminal. Let's look into
tcp_terminal.run.

  <start name="tcp_terminal" caps="200">
    <resource name="RAM" quantum="8M"/>
    <provides> <service name="Terminal"/> </provides>
    <config>
      <policy label_prefix="test-terminal_echo" port="8888"/>
      <vfs>
        <dir name="dev"> <log/> </dir>
        <dir name="socket"> <lwip dhcp="yes"/> </dir>
        <dir name="pipe"> <pipe/> </dir>
      </vfs>
      <libc stdout="/dev/log" socket="/socket" pipe="/pipe"/>
    </config>
    <route>
      <service name="Nic"> <child name="nic_router"/> </service>
      <any-service> <parent/> <any-child/> </any-service>
    </route>
  </start>

The configuration defines a policy for test-terminal_echo that can
easily be changed to the demands of your scenario.

  <policy label_prefix="vfs" port="<desired port>"/>

or even

  <policy label="vfs -> " port="<desired port>"/>


I hope this helps.
