# Helper to mount rclone-fuse from /etc/fstab.  To use, add an entry
# like:
#
# # DEVICE                                   PATH                 TYPE  OPTIONS
# rclonemount#robert#local:/data/Media2      /home/robert/test    fuse  _netdev,defaults   0 0
# rclonemount#robert#local:/data/Media2      /home/robert/test    fuse  read-only,config=/home/robert/.rclone.conf   0 0
#
# where the device field is a pound-separated list of options to pass on
# the command line.  The examples above, for example, specify that
# rclone will authenticate as robert and attempt to mount remote local:/data/Media2
# The second example also sets the read-only and 'config' option to
# '/home/robert/.rclone.conf' via the rclone command line.  Any valid
# rclone can be passed in this way.
# _net_dev can be used to tell automount to NOT mount at boot as your network
# device may not be ready yet.  If you use this option, you'd need something else
# to issue the mount command itself.  Alternatively, a sleep can be added to the rclonemount
# helper to wait before mount.
