Weekly update on the automotive-sig
by Alexander Larsson 21 Jan '22

21 Jan '22

Actually this is an update for the last two weeks, as there was no update last week. Things that happened last two weeks: * The build pipelines in the manifests dropped a bunch of packages that are not used by the images, such as filesystem support for xfs/squashfs and cdrom support. This makes the build smaller and faster and requires less packages to be supported. * There is a new makefile target extension "*.ext4" which creates an image similar to the normal one but without a multi-partition setup. This is useful on some boards where the boot happens in a non traditional way and all that is needed is the root filesystem. * There is a new makefile target "*.tar" which makes it easy to generate a tarballs containing the contents of what would otherwise be in image. * The makefiles now support passing strings with spaces in them in the DEFINES variable by escaping them with a backslash. * The two images "kernel_dev" and "osbuilder" were combined into a single "developer" image that has the content of the previous as well as some container tooling. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexander Larsson Red Hat, Inc alexl(a)redhat.com alexander.larsson(a)gmail.com

Hi Guys, I wrote a blog post describing and comparing Fedora on M1 macOS, Fedora on Android, Fedora on Raspberry Pi and Fedora on x86_64. CentOS runs on these platforms just as well. If curious see below: https://ericcurtin.wordpress.com/2022/01/14/more-than-a-pi-alternative-aarc… Is mise le meas/Regards, Eric Curtin

Good Morning Everyone, First of all, we would like to wish you all a very happy new year! May it give us the opportunity to meet with you all and see our group grow and succeed :) Here is a quick update of some of the things we have been working on this week: * Packaging Some of the libraries we have been using had been quickly packaged and made available in a copr repo. We figured it was time to have another look at them, polish their packaging and submit them to be included in Fedora and EPEL. * A container to (re)building the kernel's RPM We've been looking at ways to build a container with all the dependencies pre-installed to make it really easy to (re)build the kernel's RPM. We ended up with two methods: - One using OSBuild and the Makefile [1] This allows to build qcow2 or container images thus giving the possibility to use VM or container both with the same content - One using a more traditional approach based on a Dockerfile [2] For both approaches, once you are running the container, you can simply: - get a kernel source rpm (for example: https://cbs.centos.org/kojifiles/packages/kernel-auto/5.14.0/30.1.el9s/src/… ) - rpmbuild --rebuild kernel-auto-*.src.rpm Happy hacking, Pierre [1] https://gitlab.com/redhat/automotive/automotive-sig/-/merge_requests/97 [2] Location for that file is still being discussed but we can already make it available on this list if someone is interested/wants it earlier. Just say so :)
