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. =:^)
