I`ve install the latest version of Cubieez debian and it`s working quite well so far .
I made a rootfs partition and same size as the nand , so I can copy the rootfs back forth , but not tried copying the rootfs from the sata drive back to nand yet.
The problem I had to start with was finding password ( cubieboard ) to get in so I could edit out the network interfaces so I could get in via ssh.
I`ve installed tvheadend ( signal tuner ) , mpd / mpc , deluge and flexget and had no problem with any install , which is not what you can say with Ubuntu.
The only problem I`ve got right now is the "load average always above 1.00" . http://www.cubieforums.com/index.php/topic,1084.0.html
I tried the usb_det_vbus_gpio = "axp_ctrl" mod , and mpd just from 5% to 55% , which I think it was using the extra 50% cpu writing 1000s of error messages to the error log.
dvb-t tuner error , so I broke the usb ports with it !!!!
