Bug#1069264: grub: chooses stale RAID1 mirror over fresh mirror

Package: grub
Version: 2.06-13+deb12u1

md: kicking non-fresh <device> from array!

This is using MD-RAID1.  Appears GRUB is opting to load grub.cfg, kernel
and initial ramdisk off of this device, rather than the still operational
mirror.  The result is without manual intervention an older kernel
potentially gets loaded and causes problems.

I must argue this qualifies as "critical" since an older kernel might
have security holes or other problems.  For now I'll leave this as
"important" since I'm unsure how many are effected by this.
