Bootable system images created by scripts/mkroot.sh:
LINUX=~/linux CROSS=allnonstop scripts/mkroot.sh
Each system image is built from two packages: toybox and Linux.
Run the ./qemu-*.sh script in the tarball to boot the system
to a shell prompt under qemu. Run the "exit" command to shut down the
virtual system and exit the emulator.
See https://landley.net/toybox/FAQ.html#mkroot for details.
