Right. I reverted fstab to the previous "0 0" state and gave up
automatic checking. But I still have to find out how to do it manually
(that is, which options to pass to fsck?)

I had read the man page. It doesn't say how it does the checking, it
just says when.
Tuning the behaviour is not the issue, I'm assuming that the defaults
(corresponding to "0 2") are good enough. I just don't know what the
defaults are.
In other words, I would like to know how to do manually what fstab
does automatically.
