Thanks for the background. I agree that automatically (or even
unconditionally) redirecting its output to /dev/console would be an
improvement, even if it's not the Right Thing.

Hmm. I feel ignorant now.

But isn't it right that messages are output to the console before the
root filesystem is started? A reasonable thing to do would be to bind
that mechanism, whatever it is, to the root filesystem's stderr. Then
translators could inherit stderr from there, and no one needs to touch

Hmm, I've been assuming that passive translators inherit stdio from
their parent filesystem when they are started. But perhaps that's not
true? If they did, it would be enough to have the root filesystem open
/dev/console, pfinet would inherit that automatically.
