# Auto-reboot script for ethOS 1.2.9
# https://trick77.com/auto-restart-crashed-mining-processes-ethos
#
# This script will automatically reboot the mining rig depending on the reported
# mining status in ethOS.
# - The script should be triggered every 15 minutes from a cron job.
# - May or may not work with other ethOS versions than indicated above.
#
# This script should only be used in more or less stable rigs. Do not use it on rigs that aren't properly
# fine tuned.
# 
DRY_RUN=true # set this to false to enable auto-restart/reboot
