Yeah, we've dismissed it before, but might be worth having another look at. I don't think those values will be accurate though, as they'll depend on which file systems the respective OS support – in which case I don't think it'd make sense to put in.

I'd be interested in this as well; in all of the most common cases it's easy to get used/free from the filesystem. I'm using drivelist on an embedded linux device and one of my motivating use cases is monitoring disk usage.
