the os image builder for the tinybox.

uses ubuntu-image so should run on any recent ubuntu-based system with snap support.

run make green to build the image for tinybox green or run make red to build the image for tinybox red.

userspace/etc/tinybox-update-stage contains the current system update stage, service/autoupdate-tinybox.sh will check this file and run all update stages in service/autoupdate/ that are greater than the current stage. userspace/etc/tinybox-update-stage should be bumped manually when a breaking change is done alongside a corresponding update stage script.
