If you turn the machine off at the end of the day you will get an fsck
every 3 weeks or so (unless you are kernel-developing and rebooting
much more often). Fine.

If you have a server that runs 24/24 then you will get much less
frequent checks. Even the "check after <date>" might not get
triggered for months.

Anyway, the "nocheck" might mean that it doesn't check if all the
superblocks are the same. That is not all that important. Have it
check that the first two times you mount it, but after that there is
nothing that should be changing them. ....
