The gvfs is a virutal file system.  Gnome will use it to give non-gnome
applications access to files that are remote (network shares, ftp, sftp,
etc... any files that nautilus can see but aren't mounted as a
filesystem should be shoehorned into gvfs)  I'm not too sure why gnome
copies the root filesystem properties for spaced used/free, but that
seems to be the case for several examples I've seen.
