from Chaos Computer Club - recent audio-only feed · host Emmanuele Bassi, Martín Abente Lahaye
Updates are a critical piece of managing your fleet of devices. Nowadays, Yocto-based distributions can utilize layers for well-established update mechanisms. But, did you know that recent releases of Yocto already come with a simple update mechanism? Enter systemd-sysupdate: a mechanism capable of automatically discovering, downloading, and installing A/B-style updates. By combining it with tools like systemd-boot, we can turn it into a comprehensive alternative for common scenarios. In this talk, we will briefly introduce systemd-sysupdate, show how it can be integrated with your Yocto distribution, and share thoughts on how it can be improved further.
