The Fedora Linux 42 beta was released today[1]. The Fedora CoreOS next stream has been rebased and is currently rolling out. This is a preview of what is coming to the testing and stable streams when Fedora Linux 42 is released in the coming months.
For more information about Fedora 42, see the Fedora Project’s list of official Changes[2] and the Fedora CoreOS analysis of each Change[3].
There were a lot of changes on the Fedora CoreOS side going into this release that may require attention:
- In Fedora 42, all newly provisioned nodes will now be pulling updates from the OCI registry at quay.io/fedora/fedora-coreos [4]. In the coming months existing nodes will be migrated as well using a migration script[5]. This has the potential to cause disruption in environments where proxies or firewalls need to be updated for this change.
- In Fedora 42, CoreOS has changed the backend for almost all disk image building to use OSBuild[6][7]. We don’t expect any meaningful changes to user experience as a result of this.
- In Fedora 42, CoreOS the Live ISO/PXE artifacts were changed to use EROFS as a backing filesystem[8].
- In Fedora 42, the
pam-ssh-agentRPM has been dropped[9]. If you layered this package previously it will need to be removed before systems can be updated.
Please test out the next stream and report any issues in our issue tracker[10]!
