#  Maybe force-downgrade to last revision if it couldn't start after 3 attempts after an update?

# This is run from node which is run from cron, so we need to add a few vars to the envirnment
# TODO: Load this in using a file like "bashenv" because most nodes are going to be setup without needing SSH access to the repo
