Come to think of it, I think this may be the answer. This would be the reason
why you should set your bootloader to mount the partition with /boot (i.e.
with the kernel) as read-only. If you view your kernel messages at boot, it
will initially say that it is mounting read-only. After the kernel is loaded
and the fscks (if any) done, the partitions are mounted read-write (if
specified in /etc/fstab).
