lcd and hdmi dual display

Is there any hope of dualbooting yet?

Not in the sense of grub2 on traditional gnu+linux distributions.

... but, all I have to do to dual-boot (or quad-boot, whatever) is to pop in another SD card and power-up.  So dual booting in the sense of a desktop hard-drive is not really necessary, unless you have moved your rootfs to an ssd, hdd, or other.... and you want an easier way to get to those... but again, even so, the answer is to pop in another SD card pointing to the correct rootfs.
