hmm, doesnt debian have minimal rootfs tarballs somewhere like 
http://cdimage.ubuntu.com/ubuntu-core/daily-preinstalled/current/wily-preinstalled-core-armhf.tar.gz

that way you could avoid the writable part completely (since you dont
need to install debootstrap)

sudo apt-get install qemu-user-static ...
then use qemu-debootstrap (takes identical args to debootstrap) so you
dont need to do all the --foreign dance, way easier (oh, and you can
chroot into the created dir too if you want to try out armhf stuff on
your pc or make changes, install extra packages etc)

this part is *absolutely lovely* ... 

you should put it on the wiki somewhere :) 
(or perhaps someone could script it in a way that you can just call it
with an adb enabled device attached) :)
