Re: Multiboot Bootloaders
I imagine multiboot would be very useful if one, say, had a stable
version of Rockbox on the internal memory and a development version on
an SD card. It might also be useful for someone trying to minimize
writes to internal NAND - install once on the NAND, and install
on/boot from an SD card copy from then on.
That's all I can think of, though.
