-# meta-readonly-rootfs-overlay
-
-This OpenEmbedded layer provides the necessary scripts and configurations to
-setup a writable root file system overlay on top of a read-only root file system.
-
-## Why does this exists?
-
-Having a read-only root file system is useful for many scenarios:
-
-- Separate user specific changes from system configuration, and being able to
-find differences
-- Allow factory reset, by deleting the user specific changes
-- Have a fallback image in case the user specific changes made the root file
-system no longer bootable.
-
-Because some data on the root file system changes on first boot or while the
-system is running, just mounting the complete root file system as read-only
-breaks many applications. There are different solutions to this problem:
-
-- Symlinking/Bind mounting files and directories that could potentially change
-while the system is running to a writable partition
-- Instead of having a read-only root files system, mounting a writable overlay
-root file system, that uses a read-only file system as its base and writes
-changed data to another writable partition.
-
-To implement the first solution, the developer needs to analyse which file
-needs to change and then create symlinks for them. When doing factory reset,
-the developer needs to overwrite every file that is linked with the factory
-configuration, to avoid dangling symlinks/binds. While this is more work on the
-developer side, it might increase the security, because only files that are
-symlinked/bind-mounted can be changed. However, IMO that is better left to file
-permissions.
-
-This meta-layer provides the second solution. Here no investigation of writable
-files are needed and factory reset can be done by just deleting all files or
-formatting the writable volume.
-
-# Dependencies
-
-This layer depends on:
-
-```
-  URI: git://git.openembedded.org/bitbake
-  branch: krogoth
-```
-
-```
-  URI: git://git.openembedded.org/openembedded-core
-  layers: meta
-  branch: krogoth
-```
-
-# Patches
-
-Please submit any patches against the readonly-rootfs-overlay layer via pull
-request.
-
-
-# Table of Contents
-
-1. [Adding the readonly-rootfs-overlay layer to your build](#adding-the-readonly-rootfs-overlay-layer-to-your-build)
-1. [Read-only root filesystem](#read-only-root-filesystem)
-1. [Kernel command line parameters](#kernel-command-line-parameters)
-
-
-## Adding the readonly-rootfs-overlay layer to your build
-
-In order to use this layer, you need to make the build system aware of
-it.
-
-Assuming the readonly-rootfs-overlay layer exists at the top-level of your
-OpenEmbedded source tree, you can add it to the build system by adding the
-location of the readonly-rootfs-overlay layer to bblayers.conf, along with any
-other layers needed. e.g.:
-
-```
-  BBLAYERS ?= " \
-    /path/to/layers/meta \
-    /path/to/layers/meta-poky \
-    /path/to/layers/meta-yocto-bsp \
-    /path/to/layers/meta-readonly-rootfs-overlay \
-    "
-```
-
-To add the script to your image, just add:
-
-```
-  IMAGE_INSTALL_append = " initscripts-readonly-rootfs-overlay"
-```
-
-to your `local.conf` or image recipe. Or use
-`core-image-rorootfs-overlay-initramfs` as initrd.
-
-## Read-only root filesystem
-
-If you use this layer you do *not* need to set `read-only-rootfs` in the
-`IMAGE_FEATURES` or `EXTRA_IMAGE_FEATURES` variable.
-
-## Kernel command line parameters
-
-These examples are not meant to be complete. They just contain parameters that
-are used by the initscript of this repository. Some additional paramters might
-be necessary.
-
-### Example using initrd:
-
-```
-root=/dev/sda1 rootrw=/dev/sda2
-```
-
-This cmd line start `/sbin/init` with the `/dev/sda1` partition as the read-only
-rootfs and the `/dev/sda2` partition as the read-write persistent state.
-
-```
-root=/dev/sda1 rootrw=/dev/sda2 init=/bin/sh
-```
-
-The same as before but it now starts `/bin/sh` instead of `/sbin/init`.
-
-### Example without initrd:
-
-```
-root=/dev/sda1 rootrw=/dev/sda2 init=/init
-```
-
-This cmd line starts `/sbin/init` with `/dev/sda1` partition as the read-only
-rootfs and the `/dev/sda2` partition as the read-write persistent state. When
-using this init script without an initrd, `init=/init` has to be set.
-
-```
-root=/dev/sda1 rootrw=/dev/sda2 init=/init rootinit=/bin/sh
-```
-
-The same as before but it now starts `/bin/sh` instead of `/sbin/init`
-
-### Details
-
-`root=` specifies the read-only root file system device. If this is not
-specified, the current rootfs is used.
-
-`rootfstype=` if support for the read-only file system is not build into the
-kernel, you can specify the required module name here. It will also be used in
-the mount command.
-
-`rootoptions=` specifies the mount options of the read-only file system.
-Defaults to `noatime,nodiratime`.
-
-`rootinit=` if the `init` parameter was used to specify this init script,
-`rootinit` can be used to overwrite the default (`/sbin/init`).
-
-`rootrw=` specifies the read-write file system device. If this is not
-specified, `tmpfs` is used.
-
-`rootrwfstype=` if support for the read-write file system is not build into the
-kernel, you can specify the required module name here. It will also be used in
-the mount command.
-
-`rootrwoptions=` specifies the mount options of the read-write file system.
-Defaults to `rw,noatime,mode=755`.
-
-`rootrwreset=` set to `yes` if you want to delete all the files in the
-read-write file system prior to building the overlay root files system.

-# This script allows one to specify the root read-only device with
-# kernel argument:
-#     root=
-# What follows can be a PARTUUID, PARTLABEL, or some other mechanism
-# understood by findfs, including the plain device name.
-#
-# The rw file system overlayed on top of root defaults to:
-#     rootrw='PARTLABEL=user_data'
-# This is the first GPT partition found with the name user_data.
-#
-# Another file system can be specified by PARTUUID, or the
-# plain device name, or anything understood by findfs.
-# For instance:
-#     rootrw=/dev/mmcblk0p10
-# to use the SD card.
-#
-# fsck is not done to the root file system.  It is assumed it cannot be
-# corrupted.
-# By default, fsck -p [rootrw device] is done.
-#
-# There are two kernel options governing fsck:
-#
-# fsck.repair=true|false|force
-#    false skips fsck, force adds the -f option.
-#    true is the default (fsck with no -f option)
-# fsck.mode=preen|yes|no
-#    These represent -p, -y, and -n options.
-#    Preen (-p) is the default
