There is a patch, and a bug open, but as of today grub isn't even
building in rawhide so I've not been able to test it ...

I hope we can get it into f11 but no promises; OTOH with the default of
root on lvm, and thereby a need for a separate /boot, I'm not overly
concerned about having ext3 on /boot (compared to, say, making ext4 solid)
