Security :: Chroot Can't Find Any Files In The Jail - Error 'empty' Jail

chroot in two mini distros (Tiny Core and SliTaz): chroot jail appears 'blind'. Chroot can't find any files in the jail and exit with error code. Example (ugly):

Code:
# mkdir /mnt/test
# mkdir /mnt/test/bin
# mkdir /mnt/test/dev
# mkdir /mnt/test/proc
# mkdir /mnt/test/lib
# mount /dev/hdb1 /mnt/test
# mount -t proc none /mnt/test/proc
[Code]...

chroot: cannot execute /bin/bash: No such file or directory Where is the problem?
