This is confusing.

A common problem is that the mkinitcpio image is generated
mid-upgrade. If some component of lvm is updated before the kernel and
another is upgraded after, this may lead to broken images. We can't
prevent this from happening right now, but OTOH I haven't seen it in a
while.

To be on the safe side, run 'mkinitcpio -P' after kernel updates.
