The last couple of weeks we have been working a lot on the sample images in the automotive sig. This culminated in a lot of changes at the end of this week that are very exciting. First of all, the manifests for these images are available (just like before) at: https://gitlab.com/redhat/automotive/automotive-sig But the recent changes are: We now have images based on CentOS Stream 9. The old CentOS Stream 8 manifests still remain, but will soon be removed in favour of the new ones. We have images targeting virtual machines and Raspberry Pi4, each supporting either OSTree or regular boot mode. There is a new build tag for automotive in CBS: https://cbs.centos.org/koji/buildtargetinfo?name=automotive9s-packages-main-el9s This allows us to build custom packages targeting the automotive images that are not normally in centos. In this tag we now have builds of the new automotive kernel, and some other packages that are needed for the realtime support it has: https://cbs.centos.org/koji/packages?tagID=2463 These kernels and packages are automatically pulled into the automotive image builds. All the manifests have been converted from JSON to Yaml. This makes the manifest easier to read and maintain, and it also allows us to use comments in the manifests. The tool that reads the yaml is osbuild-mpp, which now supports either json or yaml, but it always outputs json files that are read by osbuild. We have been experimenting with booting the images without grub, using direct uefi kernel booting. This is done in order to boot faster and with less code. This work is experimental, but if you want to play with it, change the image_type to "directboot" to see this in action. It even works on the raspberry pi. All manifests are now ext4 based rather than xfs, as the automotive kernel is slated to remove the xfs support. The neptune images now automatically log in as the "neptune" user and start neptune. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexander Larsson Red Hat, Inc alexl at redhat.com alexander.larsson at gmail.com
