Creating the meta-packt_rpi layer with the yocto-layer script
To create our custom layer, we can use two different methods:
- Manually: create the directory ( - meta-*) and create the layer configuration file (- conf/layer.conf)
- * Use the - yocto-layerscript provided by the Poky environment
To 
gain flexibility 
and avoid 
mishandling, we'll use 
the second option. To use 
it, 
we must 
initially source all variables 
to gain 
access 
through our 
shell 
in the 
yocto-layer
script, as shown in 
the following command:
$ source oe-init-build-env rpi-build
Now that our 
environment is set up, we have access 
to the 
yocto-layer 
script, 
and so, 
we can begin 
the 
process of creating the layer.
Note that this script (yocto-layer) creates the layer in the current directory by default. That is 
why we must 
place it 
at the root 
of our environment:
$ cd /where/you/want/to/stored/your/layer
We can now launch the script using the following command:
$ yocto-layer create <layer_name> -o...
