The following doesn't work either.  Note that I added the bash excutable to
the ~ftp/bin directory, which is described below.

        # chroot ~ftp ~ftp/bin/bash
        chroot: cannot execute /home/ftp/bin/bash: No such file or directory

I have since added the following files/directory:

        # ls -al ~ftp/bin 
        dr-xr-xr-x   2 root     root         1024 Jan 25 11:56 .
        dr-xr-xr-x   8 root     ftp          1024 Jan 25 01:29 ..
        -r-xr-xr-x   1 root     root       490964 Jan 25 11:56 bash

Someone suggested that the reason behind chroot not working is that bash is
not under the new root, which I have attempted to correct this time around.
Unless I'm doing something very wrong, it still doesn't work.
