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-agent` RPM 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]]!
