#!/bin/sh
# File: /usr/bin/myautomountd
# Location: gitlab
# Authors: beanpole135, bgstack15
# Startdate: 2020-09-23
# Title: Automount in Shell
# Purpose: almost one-for-one translation of Go version
# History:
# 2020-09-23 translated by bgstack15 to shell from Go version (reference 1)
# Several translation notes: configuration split out into separate file
# and given a Fedora flavor.
# Usage:
# Invoke this at X startup. This can be from the xdg autostart mechanism, or "exec myautomountd &" in ~/fluxbox.startup
# This is the backend to myautomount-trayicon
# Reference:
# https://github.com/project-trident/trident-utilities/blob/master/src-go/automount/main.go
# Improve:
# Dependencies:
# udevadm (from systemd-udev or eudev)
# dep-devuan: eudev
