On mounted filesystems, df can use the statfs() system call. If df supports
checking free space on non-mounted filesystems and is used that way, it needs
sufficient permissions to read the disk device... but I'm not sure that option
should be granted to non-root anyway.

Berzerkers have the nasty habit of typing "login foo" to log out and
immediately log in as someone else. Linux is pandering to their perversion.
(...which should give you some idea of my opinion of that!)
