I do dnf upgrade any morning where something shows up as new. Today

the big kernel jump to 6.x kernel. Was not worried I guess since I just
ran the update like normal and rebooted to it.
Ended up at:

Note that this is a very "old" system, having been dnf
upgraded from
F19 all the way to today. I notice that the grub menu looks a bit
different, so it could be an issue of having an old grub on the disk
that needed an update.
Posting the above got me thinking. I have a 3 drive raided system, so I can boot from any
of sda, sdb or sdc.
I ran a grub2-install on sdb and rebooted, stopping at bios to reboot from sdc and then
sdb. Yup, each drive needed a new grub install or else it had that issue. So I am 99% sure
that this is just a case of me not having updated my grub version on disk for so long.
Let this be a reminder to people upgrading over many version of Fedora. It does not hurt
to update your grub boot sector every now and then. Maybe worth doing after each major
Fedora version update.
P.S. Thanks to Tom for confirming that this is rare.
