+ A/B updates with RAUC
+ This layer now contains one example of building an A/B update using RAUC.
+ Users are free to use/test this example, to optionally enable it, to build
+ their own update strategies based on this one, or to ignore it completely.
+ This example only works with
+
+ INIT_MANAGER = "systemd"
+
+ If you wish to use this example in your builds:
+ - enable 'systemd' as your init system
+ - add the meta-rauc layer to your build (with the corresponding branch)
+ - add 'rauc' to your DISTRO_FEATURES
+ - enable RK_RAUC_DEMO in your config
+
+ If you wish to implement your own RAUC update without using the example from
+ this layer, perform the same steps as above except for the step enabling
+ RK_RAUC_DEMO.
