No, because one cannot tell if a given path is a mount point or the device without consulting the mtab file. I meant that it would be theoretically be possible to build a umount that does roughly half of what umount usually does and that half would be equivalent to settrans -gp /foo. But this umount is fully featured and does require a mtab file to do anything. Afaict that's how umount is supposed to work. Justus
