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