When I tried to enable fsck on all FS, I discovered that calling fsck() 
at this point won't work.

This is because of the "life-cycle" of pytest fixtures works. How it is 
done today makes failure report unreliable (the error is reported for 
the test after the failed one).

I'll try to come up with something but it'll take some time to get used 
to pytest. Meanwhile I'll drop this from the  series.
