Personally, I would hit 'y', but I'm a risk taker. The fact that I've never seen e2fsck get anything wrong helps too...

IIRC, I seem to remember reading that the /var parition could be wiped at will - and that anything important gets recreated. In particular, the database gets rebuilt everytime you sync the empeg anyway. But you might want to check this information first.

Anyone else want to chime in?
