# Inspiration from https://github.com/s3fs-fuse/s3fs-fuse/issues/152
# Run from the root user's crontab to keep an eye on mount-s3 which should always
# be mounted.
#
# Note:  If getting the amazon S3 credentials from environment variables
#   these must be entered in the actual crontab file (otherwise use one
#   of the s3fs other ways of getting credentials).
