To give shorter lines easier to read [chroot-i486] root:/usr/src/coreutils-8.20$ cd / [chroot-i486] root:/$ mkdir -p a/b [chroot-i486] root:/$ mount --bind a a/b [chroot-i486] root:/$ cat /etc/mtab /dev/disk/by-uuid/7a235d64-5d04-41ac-a959-70465eb74fc8 / ext3 rw,relatime,errors=remount-ro,barrier=1,data=ordered 0 0 /a /a/b none rw,bind 0 0
I see a/b here and umount know how use that a/b entry [chroot-i486] root:/$ umount a/b [chroot-i486] root:/$ what is really missing? Gilles
