# 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.
# 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/verbose instead.
