if snappy is supposed to come to the phone and if you want snap packages
to work there for convergence reasons (i can imagine someone picking
cheap phone HW over a beaglebone for his drone project. on the phone you
get a magnitude of sensors for free; and well ... there is the "desktop
on the phone" case), then you have to deal with vendor modified BSP
kernels that are loosely based on some 3.4 android tree. 

we also aim to make it easy for vendors to port their tree themselves.
how realistic is it to offer an easy to apply patchset for all possible
base versions between 3.4 and today to bring the overlayfs bits into
such a kernel ?

could we ease that pain somehow, to attack this problem from the other
side ?

did anyone think about a fuse based solution yet ?
would that be to much of a performance hit ? 

ciao
