hi and thanks. thats not exact what i had in mind. when i.e. there is a directory /mnt/x than you can cp something into /mnt/x but when you mount something in /mnt/x than what you copied there is hidden till you umount. when creating device-nodes $LFS/dev/console and $LFS/dev/null and bind-mount host-/dev in chroot-/dev ( $LFS/dev ) than i guess, cause console and null exists in host-/dev (but the same if not) the recently created device-nodes are 'hidden' ?
