Wow... Thanks for this big patch !
Now I just add to think how to "cleanly" include it :-)

It's mandatory to use geom label on x86 for being "storage device
agnostic". If BSDRP start from an USB flash key, the drive will be
/dev/da0, but from a mSATA flash it will be /dev/ada0.
I need to check if makefs(8) or mkimg(1) supports to set a correct label on
this case.

About the UPGRADE tool on MIPS:
I had to "emulate" the concept of "MBR active partition" on sparc64
architecture. Because there is no concept of "MBR active" partition, I had
to use a new method (directly re-configuring the Sun OBP for booting on the
other partition).
How, from the userland on a MIPS platform, how to configure the boot loader
for booting to a new partition ?

I didn't have an edgerouter anymore for testing the image, but I will play
with qemu for testing the integration of your patch.

Thanks a lot's.
