For now, cleanly deactivating LVM before shutdown is not neccessary.
Otherwise bringing up LVM from an initial ram disk and switching the
root would bring the systems in trouble as there are no actions like
switching back to a ram disk on shutdown, unmount the "real" root, stop
LVM and stop the system...

Filesystems must be unmounted before shutdown. But if something crashes,
a fsck inspects the filesystem on the next system startup. I expect LVM
to behave similar if bringing LVM down before shutdown will be required.
