The Fusion MPT SCSI storage drivers were missing from the new minimal initrd because they are not together with the other storage driver modules but live in their own "message/fusion/" folder. Add the "message/fusion/" folder to the initrd modules so that we can load the disk. Dependencies will be resolved by dracut-install as needed.

Fixes flatcar/Flatcar#1924

How to use

Backport to Alpha

Testing done

Builds and the resulting image has the drivers. I didn't check if they get auto-loaded on the setup where this was a problem.

  • Changelog entries added in the respective changelog/ directory (user-facing change, bug fix, security fix, update)
  • Inspected CI output for image differences: /boot and /usr size, packages, list files for any missing binaries, kernel modules, config files, kernel modules, etc.

Very lucky that someone with this obscure hardware was running Alpha. I wonder if we've missed any others, but how to identify them? 🤔

Glancing at git grep -l "depends on.*SCSI", we probably should include at least drivers/infiniband, assuming that doesn't require extra userspace. I don't know much about it.

only by running on real baremetal :), will trigger some runs on what I have locally and report back.
