Not sure what happened to your .gitignore -- but you definitely don't
want this in the patch :-)

It probably should be mentioned though that sharing *is* possible for
network devices. The different pfinet instances will just pick the
packets applying to them, based on IP.

There is also a "proper" user-space multiplexer for network devices now,
called eth-multiplexer. This is only needed though if you also want to
allow network traffic between the Hurd instances uning the device in
question, rather than just each of them communicating with other
machines.

I don't think this really belongs here?...
