# INSTRUCTIONS. Put this file in /etc/init. Move /etc/init/tcsd.conf to
# /etc/init/tcsd.confxxx to disable it. Then boot with the device connected by
# wired ethernet. The test will start and reboot the host after every cycle.
# Unplug the ethernet cable to stop testing. If left alone, the test will stop
# at the first failure or when all the states have been tested.
#
# Reminder: rollback_index_test only works with TPM-agnostic firmware.
# Connecting to tcsd requires that "localhost" be reachable, so we wait for
# shill to start, but that's not enough, and in the while loop below we also
# wait for pinging to localhost to succeed.
