However if I use reboot, the FR starts up and I can connect to
192.168.0.202 via USB again. I then run my setup.sh from
/media/mmcblk0p1 which changes usb0 to 192.168.1.202 and sets up eth0 as
192.168.0.33 (via DHCP). I have then rebooted but usb0 remains at
192.168.0.202 and the USB link does not remain up long enough for me to
look at things (maybe because of conflict with my 192.169.0.* LAN?) -
can you do a rootfs that uses DHCP to set up eth0 so I don't need to
mess around with usb0?

I presume it also uses memory that would normally be available for
something else?

OK but would it be a good idea for normal use? Faster?
Thanks,
