Is there any possibility to selectively disable / enable background fsck 
on specified mount points?

I can imagine system, where root, /usr, /var and /tmp will be checked by 
fsck in foreground, but waiting to foreground fsck on data partitions of 
about 500GB or more (it can take up tens of minutes or "hours") is scary.
I need server with ssh running up "quickly" after the crash, so I can 
investigate what the problem was and not just sit and wait tens of 
minutes "if" machine gets online again or not... answering phone calls 
of clients in the meantime.
