We changed the deployment process by introducing a demolition squad role. Beside build.opensuse.org, we also release OBS regularly and are in charge of quality assurance using e.g. openQA and Kanku.\n\nLast but not least, we will cover how you can participate in OBS development, both as a developer and suggesting changes and features.\n\nIf you ever wondered how the OBS gets developed, this talk will provide some insights into how the OBS development works including tools we use (e.g. depfu, hakiri, codecov) and workflows we follow (e.g. Scrum).\n\nOBS developers have also changed a lot in the last time.

From the client point-of-view, Fleet Commander relies on SSSD to fetch the the profile data at users' login time and notify Fleet Commander whenever new profiles have to be applied.\n\n3) A short Demo about the current status of the project: This will be the first time that Fleet Commander project will be Demo'ed after the freeIPA/SSSD integration.\n\n4) Plans for the future: A quick discussion about what are the plans for the future, including a way to manage profile data in case of direct integration between Linux clients and Active Directory servers!","original_language":"eng","persons":["Fabiano Fidêncio"],"tags":["osc18","1663","Desktop and Applications"],"view_count":173,"promoted":false,"date":"2018-05-26T00:00:00.000+02:00","release_date":"2018-05-26T02:00:00.000+02:00","updated_at":"2025-06-25T14:00:05.206+02:00","length":1707,"duration":1707,"thumb_url":"https://static.media.ccc.de/media/events/osc/2018/1663-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/osc/2018/1663-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/osc/2018/GmtN-uEY5pV3iXBo4RxuDQ-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/osc/2018/GmtN-uEY5pV3iXBo4RxuDQ-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/1663-fleet-commander-the-efficient-way-of-managing-the-desktop-profiles-of-your-fleet","url":"https://api.media.ccc.de/public/events/GmtN-uEY5pV3iXBo4RxuDQ","conference_title":"openSUSE Conference 2018","conference_url":"https://api.media.ccc.de/public/conferences/osc18","related":[{"event_id":5501,"event_guid":"YEJOkxvQJMR7HSFH9bSSNA","weight":2},{"event_id":5511,"event_guid":"M0UgqMLHs5WPCdozDdi7BQ","weight":2},{"event_id":5513,"event_guid":"uQfyGJHP24cTJ6tMfcefbA","weight":1},{"event_id":5515,"event_guid":"4o9nYvhcvCMqkSmgEzXefQ","weight":3},{"event_id":5517,"event_guid":"zEzmm-y7I968cZsdjfWOIA","weight":2},{"event_id":5527,"event_guid":"rAlGHFVF-3UnW0IhVWOEEQ","weight":1},{"event_id":5528,"event_guid":"22g21-9kzH5VYk6hwXsmlA","weight":4},{"event_id":5534,"event_guid":"FYGInk6xUS9vg93ODzaNhw","weight":2},{"event_id":5541,"event_guid":"6S4ivpZLdGJZeHS-EG1JEg","weight":2},{"event_id":5544,"event_guid":"Vhm3GQebxdtzVPq4uFTaPA","weight":2},{"event_id":5545,"event_guid":"33a78b77-a1fa-5bf8-a719-15a8663593dd","weight":2},{"event_id":5554,"event_guid":"41ebd647-9d5f-5779-9dba-3d3623b673bb","weight":2},{"event_id":5559,"event_guid":"wH433cPdvbX3qo5fUFKgbA","weight":2},{"event_id":5567,"event_guid":"cb4WPl8YMJeHGRt-929MBQ","weight":1},{"event_id":5568,"event_guid":"9eah1LaL9DZcns3GraeyEw","weight":1}]},{"guid":"MvjuM5ztxLYRNqCdWCtUWQ","title":"Atomic Bonds: openSUSE Kubic \u0026 SUSE CaaSP","subtitle":"openSUSE \u0026 SUSE exploring the container world","slug":"1909-atomic-bonds-opensuse-kubic-suse-caasp","link":"https://c3voc.de","description":"The Kubic Project is an exciting new part of the openSUSE family.
