Alex,

Sorry for the late reply.

Is there a way to setup or detect the binfmt_misc configuration on the system?
I think it's better to error out (and hint how to fix that) if qemu-arm is not
registered. Now it only fails complaining about "wrong exec format" after the
long debootstrap process is done.
