snazzer usage of df --output incompatible with coreutils older than 8.23

user-submitted: won't run on systems with coreutils lower than 8.23 due to usage of df --output

coreutils 8.21 (Feb 2013) actually. A more compat option is df -P | awk '{print $6}'

Thanks! I actually was using df -P originally, but I was on a hell-bent mission to support hostile paths. I'll do some sed, perhaps.
