How about dropping the use of `df', at least on GNU/Linux? It's IMO
ridiculous to invoke an external program for a single system call. I
know that this system call is notoriously non-portable, and that doing
in Emacs all that system-dependent stuff that `df' does is not a good
idea. But at least on the most popular free system (and perhaps on a
few compatible ones) we could do it right without all that labor, and
gain stability and reliability that depending on `df' will never
achieve.
