7# INSTRUCTIONS.  Put this file in /etc/init.  Move /etc/init/tcsd.conf to
8# /etc/init/tcsd.confxxx to disable it.  Then boot with the device connected by
9# wired ethernet.  The test will start and reboot the host after every cycle.
10# Unplug the ethernet cable to stop testing.  If left alone, the test will stop
11# at the first failure or when all the states have been tested.

17# wait for pinging to localhost to succeed.
