People extend the volume group onto a another disk accessed by a different
controller the initrd is not updated, and then the incomplete volume group
will not mount and the computer will not run enough to fix and it

Boot disks for virtually any distro will mount a physical partition however
you need the right version of LVM, to activate it. I have done updates on a
server and found when i needed to use a boot disk that it would not mount
it, which a physical root you can fix it up so at least that boots, get it
to dump you to single user and fix the rest of it.
