Multi-node ARM overlay installation

An overlay installation replaces some parts of your current OS installation or some parts of your system. In this case, when you use the rootfs k3OS file to perform this kind of installation, you will overwrite the /sbin/init; then, when you reboot your ARM device, the user space will be initialized and k3OS will be loaded. This kind of installation is supported for ARMv7 and ARM64 devices. An important thing is that you can customize this installation using the config YAML files, which must be stored on /k3os/system/config.yaml.

Before performing this overlay installation, you need the following:

An ARMv7 or ARM64 device, such as a Raspberry PI with Ubuntu 20.04 LTS installed (you can use Raspberry PI Imager or balenaEtcher; check Chapter 3, K3s Advanced Configurations and Management for reference)
A network device connection with access to the internet and Dynamic Host Configuration Protocol (DHCP) to auto-assign an IP to your device
An HDMI port...
