# This script makes autotest client tests inside an Ubuntu chroot
# environment.  The idea is to compile any platform-dependent autotest
# client tests in the build environment, since client systems under
# test lack the proper toolchain.
#
# The user can later run autotest against an ssh enabled test client system, or
# install the compiled client tests directly onto the rootfs image, using
# mod_image_for_test.sh.
