Ah yes, that could be possible. I shall investigate.
Re wicd - I want to maintain control by static configuration (in
/e/n/i), and absolutely minimise auto-configuration.
For example, when I need to test (or use as a one-shot) DHCP, I
ifdown $eth then:
dhclient -d $eth
(-d keeps it in the foreground, and logs are splendiforously
displayed in real time, in the tty I start it from).
