Hmm, good point:
Filesystem 1024-blocks Used Available Capacity Mounted on /dev/sda6 841616 4508 837108 1% /tmp /dev/sda7 124407 63774 54209 54% /var /dev/sdb5 855138 677328 177810 79% /home /dev/sdc7 4191237 3946214 245023 94% /usr
My thinking was that I've managed to run out of space on all of the partitions in the past and had to prune a lot of stuff... so nearly all the blocks should contain at least some "likely" data. Still, I guess I need to verify that this isn't distorting the results. The program needs to recurse over all files on the filesystem rather than all blocks on a partition.
