This doesn't seem to work (tried only with dizzy).
The only way I could get this to work is to extract both the rootfs and the rootfs-dbg into the same place and then set sysroot to that location.
Is this the way it is supposed to be?

I'm currently using dizzy. I will give it another try with jethro next week maybe it is working there.
