        Hello.  Actually, as I think about it, the situation where the boot
filesystem is different from the root filesystem isn't all that uncommon at
all.  Any machine that uses a raid5 set as the root filesystem, is, by
definition, not booting from the same filesystem as the root filesystem.
What should be done in that case?
