# This template creates a complete Debian system which is more streamlined 
# than the base.tgz used for normal installations.  Once everything is made, 
# you can use user-mode-linux to tweak the system, as well as apt. 
# Make-debian generates all the information you need, you will need swim and 
# file-rc installed, and you will have to be running a Debian system to make 
# this template.  Make-debian ditches info, man, and doc files by default,
# use the "doc" option to make documentation.  

# Characteristics:  user: root passwd: root 
                    user: user passwd: user
		    Uses devfs.
    
# Alternatives aren't working so you will have to use the real name like
# nvi for vi and w.procps for w.  Not all libs are associate with packages
# but that isn't a big deal.

# IMPORTANT NOTE:  Things slow down noticeably when the buffer gets too big in
# the verbosity box so consider closing it with the slider for faster 
# generation.  Look at /tmp/verbosity instead.
