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' ?
