rauc

A very fine sense of timing to release this one year after KDE 6.4 was released! https://kde.org/announcements/plasma/6/6.4.0/ . Here in 2026, KDE 6.7 just dropped. I'm still super excited for this release. KDE 6.4.3 from 6.2.5 is a nice jump. I'm very excited to get Wayland here, which is my normal baseline. Maybe this time I'll try to get Niri running on this desktop. This is one of my daily driver systems, with a monitor plugged in. I'm typing on it now. I've been holed up on on 3.7.14, build id 20250701.1, since I don't want to lose the desktop, but this one seems worth losing my desktop for. Nothing but respect for Valve for working on ruac, a very nice A/B system image switcher, that powers all these updates, even if it means I'm about to lose this desktop. https://github.com/rauc/rauc

I quit my job before I got to deploy this, but RAUC looked like it would handle this for Yocto: https://github.com/rauc/rauc https://github.com/rauc/meta-rauc For microcontrollers, Memfault had a good article: https://interrupt.memfault.com/blog/device-firmware-update-c...

I don't think security is something automatic, but I'm open to other opinions about this. If a firm is not willing to update my device anymore, why does an "automatically updated base" make me more safe? Without updates to the upper layers of the software stack I'm still vulnerable.. Is there a real advantage over Yocto plus un update mechanism such as rauc [https://github.com/rauc/rauc] or mender [https://github.com/mendersoftware/mender] ?
