-#  Read-only Root-FS for Raspian using overlayfs
-#  Version 1.1:
-#  Changed to use /proc/mounts rathern than /etc/fstab for deriving the root filesystem.
-#
-#  Version 1:
-#  Created 2017 by Pascal Suter @ DALCO AG, Switzerland to work on Raspian as custom init script
-#  (raspbian does not use an initramfs on boot)
-#

-#  Tested with Raspbian mini, 2017-01-11
-#
-#  This script will mount the root filesystem read-only and overlay it with a temporary tempfs
-#  which is read-write mounted. This is done using the overlayFS which is part of the linux kernel
-#  since version 3.18.
-#  when this script is in use, all changes made to anywhere in the root filesystem mount will be lost
-#  upon reboot of the system. The SD card will only be accessed as read-only drive, which significantly
-#  helps to prolong its life and prevent filesystem coruption in environments where the system is usually
-#  not shut down properly
-#
-#  Install:
-#  copy this script to /sbin/overlayRoot.sh and add "init=/sbin/overlayRoot.sh" to the cmdline.txt
-#  file in the raspbian image's boot partition.
-#  I strongly recommend to disable swapping before using this. it will work with swap but that just does
-#  not make sens as the swap file will be stored in the tempfs which again resides in the ram.
-#  run these commands on the booted raspberry pi BEFORE you set the init=/sbin/overlayRoot.sh boot option:
-#  sudo dphys-swapfile swapoff
-#  sudo dphys-swapfile uninstall
-#  sudo update-rc.d dphys-swapfile remove
-#
-#  To install software, run upgrades and do other changes to the raspberry setup, simply remove the init=
-#  entry from the cmdline.txt file and reboot, make the changes, add the init= entry and reboot once more.
