This is a problem: in the installation instructions, we tell people to
configure networking (possibly wireless) by hand, so we cannot expect
the DHCP client to work directly when the image is booted.

Also, the installation instructions would need to be updated.

However, what we could do, instead, is to add an SSH service that is off
by default (with (start? #f)) and does not depend on ‘networking’.  That
way, people would only need to type

  herd start ssh-daemon

to get the thing up and running.  WDYT?

I agree with others that we should use OpenSSH here.  :-)

Thanks,
Ludo’.
