poky/scripts/runqemu-extract-sdk

#!/bin/bash

This utility extracts an SDK image tarball using pseudo, and stores

the pseudo database in var/pseudo within the rootfs. If you want to

boot QEMU using an nfsroot, you must use this script to create the

rootfs to ensure it is done correctly with pseudo.
