An Ubuntu for a 10 ton steel press and your window shades
summary
Ubuntu Core is an OS built entirely from snaps: each app or component is a gpg-signed squashfs image that stays read-only, bundles its dependencies or uses content snaps, and runs confined by kernel features. Device images assemble from gadget / kernel / core snaps using the Ubuntu image tool and snapcraft. Upgrades are transactional with automatic rollbacks if a kernel snap panics, and updates send only binary diffs to save bandwidth; example: a Kodi appliance on Raspberry Pi boots and auto-connects with these pieces working end-to-end.
