Features like optional transfers, delta updates, and major version upgrades.\n\nGNOME OS is an experimental Linux distribution that ships the latest in-development GNOME desktop, core applications, and stack. It serves as a reference for developers and testers. This operating system is designed and built around the modern systemd and GNU-based userland built from the Freedesktop SDK.\n\nCurrently, GNOME OS uses OSTree to deploy the root filesystem and manage updates. This means that the base OS is immutable (read-only) and updates can be quickly downloaded as deltas. OSTree allows easy rollback to multiple previous versions of the root filesystem, which is essential for a testing-first distribution focused on finding bugs.\n\nOur work focuses on transitioning GNOME OS to use systemd-sysupdate. Migrating to sysupdate would bring the following benefits:\n* Provide a trust chain from the bootloader, all the way up, both online and offline;\n* Achieve a closer integration with systemd;\n* Advance our support for image-based design and its benefits, e.g., immutability, auto-updating, adaptability, factory reset, uniformity and other modernised security properties around image-based OSes.\n\nFor that, we are adding a number of features to systemd-sysupdate to make it more production ready; \n* Implement optional transfers in systemd-sysupdate\n* sysupdate should allow upgrading to a newer major version\n* pluggable backends for systemd-sysupdate (or systemd-import)\n\nThis project was partly inspired by Lennart Pottering's article \"Brave New Trusted Boot World\", in which he explains a vision of the future of Linux systems.\n\nLicensed to the public under https://creativecommons.org/licenses/by/4.0/de/","original_language":"eng","persons":["Abderrahim Kitouni","Jude Onyenegecha"],"tags":["285","asg2024","Dome","2024","Day 2"],"view_count":124,"promoted":false,"date":"2024-09-26T17:00:00.000+02:00","release_date":"2024-09-26T00:00:00.000+02:00","updated_at":"2026-02-28T16:45:04.699+01:00","length":1464,"duration":1464,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2024/285-a860711f-14c4-5356-92ec-2cb976444e3d.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2024/285-a860711f-14c4-5356-92ec-2cb976444e3d_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2024/285-a860711f-14c4-5356-92ec-2cb976444e3d.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2024/285-a860711f-14c4-5356-92ec-2cb976444e3d.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/all-systems-go-2024-285-gnome-os-systemd-sysupdate","url":"https://api.media.ccc.de/public/events/a860711f-14c4-5356-92ec-2cb976444e3d","conference_title":"All Systems Go!
