sorry for partly hijacking this thread but i'm a bit curious about the 
current status of this board since i recently got one myself.

at the moment i'm running the stock firmware and i have to say it is 
quite nice but there are some downsides and things i'm missing from 
lede/openwrt side and same goes for running lede/openwrt it has some 
really good parts but it is missing some stuff from stock firmware.

one thing i miss from lede/openwrt is the ease of setting up 6rd, tried 
it on edgeos and got it partly working but not very well so i gave up.

so i don't know if i want to swap over to lede/openwrt permanently (more 
or less) and it would have been really nice if you could have one of the 
two running firmware as lede/openwrt and the other one as the built in 
edgeos and then easily swap between them.

i assume there is some technical reason for why you can't have both.
can someone explain why?
is it the squashfs root on ubifs ?


if it was possible to easily run both and swap between them i would 
change right away and give lede a try.
yes i know my way around electronics and can probably hookup the serial 
port and get that working but helps if i don't have to and have an easy 
way to fall back in case i screw-up
