need help with chroot

["Thomas H. George" <lists@tomgeorge.info>]

The man page and a google search gave minimum info except for the link 
to www.debian.org/doc/manuals/reference/ch-tip.en.html.  Following by 
rote the prompts in 8.6.35.1 I think I succeeded in installing a minimal 
Etch installation though the prompt never changed to chroot # when I 
entered chroot /bkup/etch-root /bin/bash and a subsequent command 
apt-setup was unknown.  (I started by making the directory 
/bkup/etch-root as I have lots of hard drive space in /bkup while 66% of 
/ is used.)


Next I proceeded to 8.6.35.2 again following the instructions by rote.  
Now Ctl-Alt F8 allows a login as root with no password to an empty 
directory.

Is there a good thorough exposition of the uses of chroot?
