ArcadeOS is an appliance-style OS for arcade cabinets based on ParticleOS.
The ArcadeOS image is built using mkosi. To
build the image, run ./mkosi -f from the ArcadeOS repository.
It's recommended to set a root password (e.g. via mkosi.rootpw or
RootPassword= in mkosi.local.conf), as otherwise systemd-firstboot will
prompt for one on startup, but the prompt won't be visible due to the boot
splash unless that's dismissed.
