sosa@'s statefuldev change, which installs all developer packages on the stateful partition and has put /var there as well, means that we can no longer just mount the rootfs on a usb stick and emerge packages onto/off of the removeable device. We now need to mount the stateful partition as well, and also bindmount from /var on the rootfs to /var on the stateful partition. All portage state is stored there, among other things.
