I have heard multiple requests for making general SD card (or USB stick)
style images so I would love to see something generic. The script as it
stands looks like it has some issues due to requiring root access
(and/or special mounts).

There was a previous attempt at this in OE-Core:

http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/classes/boot-directdisk.bbclass

but this has some issues making assumptions about sector size that
caused problems. On the  plus side it demonstrated it was possible
without root...

Cheers,
