Max 10 dual boot

Anyone tried out the new Max 10 devices yet? They look interesting but I have hit a brick wall regarding the dual boot and remote update of the internal configuration flash.

The dual boot example works ok in that you can successfully program two simple designs into the device using the Quartus programmer but I can't create a working design that will allow self update of the internal flash.

The basic problem seems to be that if you are using the dual boot functionality, you cannot implement ram/rom content initialisation, which means it's not possible to create something like a nios core with a boot rom. So although there are dual boot and on chip flash ip blocks available in qsys, what do you drive them with?

Maybe I'm missing something - any insights appreciated.
