a quick and dirty script to enable systemd.automount + sshfs

create_simple_automount.sh

#!/usr/bin/bash

# This script assumes you
#
#   - use key to authorize
#   - have an entry in known hosts file (eg. ssh to remote host once)
#
# You should check the "Options=" line to add or change sshfs/fuse options, especially 
# the path to key file (default to "${HOME}/.ssh/id_ed25519") and known_hosts file.
