I am not sure if this is possible or not but here goes. If this "Unraid NE" does come around, would it be possible for the system to boot like it does now to a bare-metal version of UNraid then through the webGUI, setup and partition a hard drive for UNraid NE built on CentOS with no DE but with a SSH/Telnet access. Then change the boot order on the USB stick to default to the UNraid NE unless user selects differently. From there, if things go south, a user then could select traditional UNraid during boot then either reformat the OS drive or perform necessary fixes to get it back to working state. I figured this would be the best way for all new and old users of UNraid to have the option of appliance UNraid or UNraid NE based on preferences.
