# This script mounts automatically the remote RozoFS volume defined by a
# cluster built by Docker, given few parameters as the name of the exportd
# container, exportd path and mountpoint path.

# It expects the user to give the mount path as a parameter. The following
# returns $1 if the user gives a non-null parameter, or prints the message and
# aborts the script.
