add layer meta-netboot to enable network boot over NBD (Network Block Device)
To enable the build of network bootable images, the following line must be added to conf/local.conf: INHERIT += "netboot" This layer contains recipes for the following components: * busybox: activate the built-in NBD client * initramfs-netboot: contains the init script started by the kernel, responsible for mounting the remote root filesystem then pivoting and exec'ing systemd * initramfs-netboot-image: image to specify for building the initrd More details are available in meta-netboot/README.
