What I thought you meant was the drange= or vrange= filters, changing the range to eventually cover the entire filesystem. That should work too, tho I've never actually used it myself and I suspect I'd have to play around with the ranges a bit to figure out what numbers I should actually be supplying, as the filter descriptions in the manpage are somewhat vague on this point. (Anyone who knows where to actually find those numbers to plug in and/or has useful examples, feel free to consider this an invitation to elucidate. =:^) -- Duncan - List replies preferred.
