    168 === Ubuntu Core ===
    169 Ubuntu has supported [http://cdimage.ubuntu.com/ubuntu-core/releases Ubuntu core] builds for the ARMv7 Application Processor family (Cortex A8, A9, and above with hardware float) since the 12.04 (Precise Pangolin) releases. Canocial provides multiple images that contain differing functionality (desktop, server, cloud, etc). Since 12.04 they have been providing a 'core' image (Ubuntu Core) which is a minimal rootfs for the use in the creation of custom images for specific needs. This is a suitable rootfs to start with. To deploy Ubuntu Core you need to use an Ubuntu Core rootfs from [http://cdimage.ubuntu.com/ubuntu-core/releases/ here], and a Ventana kernel (kernel + device-tree dtbs + modules).

    171 Notes:
    172  * Ubuntu Core ships with no local users, therefore you will need to add a local user and passwd then add that user to adm and sudo groups manually before booting the image
    173  * You can use apt-get to install additional packages
