# Test system image(s) (by booting qemu with -hda test.img providing /mnt/init)
# and check that:
#
# A) it boots and runs our code (which means /dev/hda works)
# B) the clock is set sanely ("make" is unhappy when source newer than output)
# C) it can talk to the virtual network
#
# Each successful test prints a === line, and all 3 means it passed.
# Writes result into root/build/test/$TARGET-test.txt
#
# With arguments, tests those targets (verbosely). With no arguments, tests
# each target with a linux-kernel (in parallel) and prints pass/fail summary.
