What's the advantage of doing this, as opposed to this:
classes:
HomePart = ( ReturnsZero(/bin/sh -c "df -l | grep '^/dev' | awk '{print $NF}'
| grep -q '^/home$'") )
As far as I can see, that should do the same with less code. Plus, by
adding '$' to the end of the regex in the last grep, you avoid a false
positive on stuff like /home/a and /home/b (large sites often have to
split /home on multiple disks).
