> Thank you Robert! That is very helpful. For my wired NIC connections interfaces is dead simple. I can see the advantage of connman for wifi.
Yeah, today for a wired connection, not using "connman" works fine.
But there was a time about 2-3 years ago.. That Debian/Ubuntu had a
really crappy ifupdown network setting, that forced you into a 2
minute wait (timeout) on bootup before the login prompt would become
available... Unless your ethernet port was connected, then login
appeared instantly..
Swapping from "auto eth0" to "allow-hotplug eth0" made zero difference
at the time. I remember supporting 2 boards with one image back
then.. The original BeagleBoard (with no default ethernet) and the xM
with a usb-ethernet adapter.. It really sucked trying to support that
configuration, as we had to have "eth0" defined in
/etc/network/interfaces so the xM would have working ethernet. Yet at
the same time hack up teh ifup scripts to remove the 2 minute timeout
so the non ethernet BeagleBoard, would still bootup quiclly to a login
prompt.
Once we swapped to connman, connman took care of those two cases pretty easily..
