Socat as configured would exit on client disconnect. Since there was
no active process monitoring, the process would (a) become a zombie,
and (b) would not restart, which would disable console access.
This commits adds the fork,max-children=1 parametesr to the socat
call, which makes socat persistent until it is explicitly killed.
