Hi,
I was moving form an raspberry pi to the Odroid C2 and wanted to keep my /storage on usb drive so i have edited the boot.ini and the config.ini to allow this as follows.
I added an option test to boot.ini as it would be good not to have to edit it manually after every update.
Code: config.ini

booti ${kernel_addr} - ${dtb_addr}boot.ini change at line 40
I guess boot=UUID=@BOOT_UUID@ should be used on line 40 as well for installation
I also think it would be better to use disk=label=usb_storage or some variation of this and make instructions in config clear that disk label must be usb_storage, however I could not get it to work.
