That's what I tried to explain in the paragraph before (before what you
quoted):
"More precisely: You never know if any
checksums taken on a running system are reported correctly. But: If you
take an online system (powered up), take checksums of important files or
partitions, and they are the same after the system later becomes offline
(powered down), then they were reported correctly to begin with. Whereas
if they were correct before running it and are then are reported correct
while the system is running, it does not tell you anything."

Good idea. I now turned off the fstab checks and also both entries with
tune2fs. Since nothing on the /boot partition is allowed to change, fsck
serves no purpose any longer. More precisely, the change detector must
notice anything anyway that fsck would see.
