Hello Genodians

I use `run/bash` and added a simple component that logs the content of a
ROM module:

```xml
<start name="test-update">
        <resource name="RAM" quantum="2M"/>
        <route>
                <service name="ROM" label="test.config">
                        <child name="vfs_rom" label="tmp/test.config"/>
                </service>
                <any-service> <parent/> <any-child/> </any-service>
        </route>
</start>
```

Then, I execute the following commands on the interactive shell:

```bash
> echo "1st-cfg"    > /tmp/test.config` # "1st-cfg" is logged
> mv /tmp/test.config /tmp/test.backup` # nothing is logged
> echo "2nd-cfg"    > /tmp/test.config` # nothing is logged
> echo "3rd-cfg"    > /tmp/test.backup` # "3rd-cfg" is logged
```

Is it the intended behavior that `fs_rom` "follows" the file or should
it always provide the ROM content of the file with the specified name
instead?

The background of this question is that in fact, `test-update` for
example could be a component that consumes the `test.config` and is
supposed to react on configuration updates.


Cheers, Roman
