Ubuntu Core: A Secured Embedded Linux Distribution for RISC-V
summary
Ubuntu Core runs on RISC-V with a real QEMU image and board ports, using kernel snap plus a per-board gadget snap and snapd to deliver a 200 MB-ish immutable base (core20/core22). Builds use snapcraft to produce an image; updates check every six hours with atomic installs, automatic rollback on boot failure, and per-app writable-data snapshots for safe rollbacks. Demo shows LXD containers running Ubuntu 22.04 on RISC-V and a small robot controlled from a RISC-V board, with secure-boot and sealed-key encryption support.
