26 Mar '24

The Fedora Linux 40 Beta was released today[[1]] and our Fedora CoreOS `next` stream has been migrated to Fedora Linux 40 content. Existing nodes on the `next` stream will update as normal over the following days. The Fedora Project accepted changes for Fedora 40 are in the Wiki[[2]] and the Fedora CoreOS analysis of each change is documented in the tracker[[3]]. The following changes require special attention: - Podman v5.0 - https://fedoraproject.org/wiki/Changes/Podman5 - https://github.com/coreos/fedora-coreos-tracker/issues/1629 The following changes may impact some specific setups: - Switch to using OSBuild for most CoreOS boot image building - Newly deployed `qemu` or bare `metal` systems will use disk images built using OSBuild. - https://github.com/coreos/fedora-coreos-tracker/issues/1653 - Enable IPv4 Address Conflict Detection by default - Conflict detection can delay startup by ~200ms. - https://fedoraproject.org/wiki/Changes/Enable_IPv4_Address_Conflict_Detecti… - https://github.com/coreos/fedora-coreos-tracker/issues/1656 - Assign individual, stable MAC addresses for Wi-Fi connections - If you are using WiFi, then your systems MAC address will likely change after the update. - https://fedoraproject.org/wiki/Changes/StableSSIDMACAddress - Switch pam_userdb from BerkeleyDB to GDBM - If you have overlayed vsftpd on your systems and use pam_userdb, then you need to convert the database using the instructions from [pam_userdb](https://docs.fedoraproject.org/en-US/fedora/rawhide/system-admi…. - https://fedoraproject.org/wiki/Changes/PamBerkeleyDBtoGdbm - https://github.com/coreos/fedora-coreos-tracker/issues/1634 Please test out the `next` stream over the coming weeks and report any issues in our issue tracker[[4]]. Thank you to everyone helping find issues by running the `next` stream!
