Now that we have a functional application (webserver-packt), we can add it to our custom image, raspberry-pack-image:

# Base this image on core-image-minimal 
include recipes-core/images/core-image-minimal.bb 
DESCRIPTION = "Image for raspberry-pi" 
IMAGE_FEATURES += "ssh-server-dropbear splash" 
# Include modules in rootfs 
IMAGE_INSTALL += "  
    kernel-modules  
    gpio-packt     
    i2c-tools     
    spitools     
    nunchuck     
    v4l-utils     
    nodejs     
    webserver-packt  
    " 

After doing this, we can start creating our image and then mount it on an SD card:

$ bitbake raspberry-packt-image
