Weekly update on the automotive-sig

Good Morning Everyone, So here are some of the changes that we have worked on this week: * We worked on some documentation about the different places you can contribute packages in our ecosystem: Fedora, EPEL, the Automotive SIG and AutoSD, cf: https://sigs.centos.org/automotive/contributing/building_packages/ * The general documentation about best practices for SIGs to use gitlab has been merged: https://sigs.centos.org/guide/gitlab/ * We have added explicitly the linux-firmware-automotive package to content resolver to replace the linux-firmware package with the aim to reduce the image size by dropping the firmware that aren't relevant, cf: https://github.com/minimization/content-resolver-input/pull/709 * We added some documentation on how you can use single-file offline ostree updates: https://sigs.centos.org/automotive/building/updating_ostree/#offline-delta-… * The example rpms that were in the sample-image repostitory have been moved to https://gitlab.com/CentOS/automotive/rpms, and the COPR repo where they used to be built has been removed from the manifests. * The manifests have changed to defaulting to static_uuids=true, where it was false before. This means repeated builds of the same image will be more reproducible, although the uuids will not be unique between builds. * Some initial support for encrypting the root filesystem with LUKS was added. Expect more work on this later though. * We improved our documentation on customizing OSbuild templates: https://sigs.centos.org/automotive/building/customize_template/ Happy hacking! Pierre

Good Morning Everyone, So here are some of the changes that we have worked on last week: * We have migrated under the centos namespace on gitlab.com: https://gitlab.com/CentOS/automotive * The new location for the kernel sources: https://gitlab.com/CentOS/automotive/src/kernel/kernel-automotive-9 * The git part of dist-git for the kernel-automotive package: https://gitlab.com/CentOS/automotive/rpms/kernel-automotive * We have split the content of the automotive-sig repository into two repositories: * The SIG's documentation: https://gitlab.com/CentOS/automotive/sig-docs * The sample images (manifests, docs, tools, demos...): https://gitlab.com/CentOS/automotive/sample-images * We have archived https://gitlab.com/redhat/automotive/automotive-sig (so update your bookmarks!) Happy hacking! Pierre

Good Morning Everyone, So here are some of the changes that we have worked on this week: * You can now override the os version field in the ostree commit in the images using the `ostree_os_version` variable. * The runvm script now supports the `--watchdog` argument, which implements an external watchdog that survives across VM resets. * There is a new image that demonstrates how the watchdog can be used to implement unattended OSTree updates. See https://sigs.centos.org/automotive/building/unattended_updates/ for docs about this. * There were various fixes to the grub configuration to support the above. Happy hacking!

Good Morning Everyone, So here are some of the changes that we have worked on over the last couple of weeks: * We have worked on the osbuild templates and the repository structure to make them more flexible and less cs9 specific. This moves the configuration for the base cs9 stuff to a separate file distro/cs9.ipp.yml, and allows you to easily create similar setups for other distros (such as the AutoSD repos) which automatically creates the right makefile targets for them. Etc. * The work to enable a new lookaside cache structure is progressing: it has been updated and we confirmed that we can upload to it, but CBS still needs a little adjustment before it can use it (code is written, just needs to be deployed) * Started drafing the best-practices doc for using the centos namespace on gitlab.com: https://git.centos.org/centos/sig-guide/pull-request/4 * We greatly improved our suppport for OSTree repository use. The Makefile makes it easy to create and maintain a repo, and the runvm changes makes it easy to allow VMs to access that repo. The new docs give more context about what OSTree is and how it works. See https://sigs.centos.org/automotive/building/updating_ostree/ for more details! * Some changes in the OSTree image type. We now use bootloader=none, which means the grub config is not rewritten on each update. There is now an ostree remote configured, and it is used as the main origin for the ostree ref that was used, allowing for updates out of the box. The url for the remote is configurable with a variable. * The automotive SIG signed up for early access to gitlab.com/centos and help the CentOS infra team to smooth the edges there Happy hacking! -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexander Larsson Red Hat, Inc alexl(a)redhat.com alexander.larsson(a)gmail.com
