I booted the MeeGo rescue initrd, enabled USB networking. Result: the network applet in the notification area is continuously a running circle, the exported partitions are not detected (a connection can't be established). Once it finishes running, the applet shows "Nokia N900: disconnected" and after a while starts running again.

The same happens if I enable usb networking in rescueOS.

How can I then expose the whole EMMC (including optfs) so that I can use gparted? I only want to increase the size of the optfs to ~6GB
