Filesystem layout

VyOS is using quite unusual filesystem layout.

The system is located on a single partition.

The system partition contains the following directories (for an image named "image"):

/boot
    /grub
    /image
        image.squashfs
        live-rw/
        <kernel, initrd, and other typical /boot contents>

Every image gets its own directory, named the same to image name. When the system boots, squashfs image and live-rw are mounted in a union filesystem.
