Pengutronix at All Systems Go!

This years All Systems Go! will take place on 25. and 26.09.2024 in Berlin. The ASG is a conference about low-level user-space topics. We are happy to contribute a talk about updating systems using RAUC and composefs:

Jan: Efficient RAUC Updates using composefs

📅 Date: 25.09.2024
🕒 Time: 18:00 (CEST)
📍 Location: Main Hall

Traditionally, RAUC focused on A/B updates for whole partitions, either by using filesystem images or tar archives. While the image-based OS approach has many benefits, there are scenarios where more loosely coupled components need to be handle in addition to the root filesystem. In RAUC, these can be handled with using the new "artifact updates" support.

As a system might have many artifacts installed in parallel, such as for containers (systemd-nspawn or otherwise) and systemd-sysexts, efficient storage is important. In many cases, these are updated often, so download efficiency is important as well.

After evaluating multiple alternatives, we've now decided to integrate composefs. Besides solving the requirements above, it additionally provides the same level of integrity protection as a dm-verity root filesystem, which is important in systems using secure boot.

This talk will show how RAUC uses libcomposefs and the new use-cases supported by having an efficient content-addressed backing store with full authentication.

More Conferences in September: Yocto Project Developer Day and KiCon Europe

September 2024 brings a wide variety of conferences: Pengutronix will present talks at the ELCE, Linux Plumbers Conference and All Systems Go. Additionally we will attend two more conferences: The Yocto Project Developer Day in Vienna and the KiCon Europe in Bochum.


Pengutronix at the Linux Plumbers Conference

The Linux Plumbers Conference 2024 will take place in Vienna from 18. to 20.09.2024. Luckily this does not overlap with the ELCE. Pengutronix will attend the LPC with six colleagues - so watch out for our T-shirts and hoodies and and feel free to chat with us.


Pengutronix at Open Source Summit Europe and Embedded Linux Conference Europe

The Embedded Linux Conference Europe is Pengutronix' most important conference of the year. It is a good place to meet new faces in the embedded community, discuss current topics and future developments with maintainers and developers - and of course: have a beer with old friends. As usual, many Pengutronix colleagues will attend: this year we'll have a 14 person team on site. So watch out for our T-shirts and hoodies and and feel free to chat with us.
