#H# This script is designed to be used in a remote rsync situation where rsync was run with:
#H# rsync --rsync-path="/path/to/rsync-if-mounted"
#H# This will cause rsync to fail if the remote path is not a mounted filesystem.
#H# Unlike other similar scripts this one works whether the remote is the source or target.
#H# Currently relies on /proc/mounts.
