Hey folks! Just a heads up on a fairly significant problem we’re working on: Right now, probably any x86_64 BIOS network install of Fedora 38 or Fedora 39 that uses an XFS-formatted /boot will fail to boot after install. This particularly affects Server, since Server defaults to XFS for /boot.
This seems to be 2259266 – grub2-2.06-117.fc40 breaks boot of installs with XFS-formatted /boot on BIOS with xfsprogs 6.5.0 suddenly affecting stable releases. That was initially found and mitigated on Rawhide, and we thought the corresponding updates for F38 and F39 didn’t have the same problem because those distros have older versions of other relevant packages, but now it looks like they did. Those updates were pushed stable last week after some delay.
Existing installs should not be affected by this (so it should be safe to upgrade your existing install), because we don’t actually reinstall the bootloader on grub2 updates (though if you were to manually do so after updating on a system with XFS /boot, it might break). Fresh installs from the Server DVD, or installs that don’t use XFS /boot, should also be fine. It’s just fresh installs that use the network repositories that are affected, I believe.
