Hi list, % jarjarbinks:/mnt/msdos:129# echo $PWD % /mnt/msdos % jarjarbinks:/mnt/msdos:130# mount -t msdosfs % /dev/ad0s5 on /mnt/msdos (msdosfs, local) % jarjarbinks:/mnt/msdos:131# mount -t msdosfs /dev/da0s1 /mnt/msdos/ % jarjarbinks:/mnt/msdos:132# mount -t msdosfs % /dev/ad0s5 on /mnt/msdos (msdosfs, local) % /dev/da0s1 on /mnt/msdos (msdosfs, local) % jarjarbinks:/mnt/msdos:133# umount /mnt/msdos/ % umount: unmount of /mnt/msdos failed: Device busy Whilst the current shell current directory vnode (I'm not sure I'm totally right here) is still the lower mount point (/dev/ad0s5), umount(8) refuses to umount the upper mount point.
