# Generated by make_debian-X11.
# This template creates a complete Debian system which is more streamlined
# than the base.tgz used for normal installations with the addition of X11.
# Once everything is made, you can use user-mode-linux and apt to tweak the
# system. Make-debian generates all the information you need. You will need
# dswim 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 and timezone info not found on the host system, but gives you
# the choice to decide otherwise.
# 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/gbootroot_tmp'time-date'/verbose instead.
#
# The windows will appear to freeze up while using this template, this is
# natural, be patient, because it will complete. If you want to create
# another filesystem concurrently, open up another invocation of gBootRoot.
# Todays Quote: Creating a root filesystem is all about stuff.

# --------------------------------------------------------------------
# Jonathan's personal directions
# This creates a X11 filesystem.
# These replacements are unique and not found in CVS:
# add sources.list to this, too.
#/usr/X11R6/bin/startx <= Replacements/usr/X11R6/bin/startx-debian-X11
#/root/README <= Replacements/root/README-debian-X11
#/root/make_swapfile <= Replacements/root/make_swapfile
#/root/umlnet <= Replacements/root/umlnet .. won't use.
#/etc/apt/sources.list <= Replacements/etc/sources.list .. for adm.
# setup script does this
# 0. run dpkg-reconfigure for xfree86-common and xserver-common.
# This catches mistakes.
# 1. dpkg-reconfigure for xfonts-base
# 2. make permissions correct for directory /home/user and all files * & .*.
# 3. run dswim --initdb .. this is done by make-debian-x11.
# 4. run /etc/cron.daily/find
# ...................................................................
# debian_x11 sourceforge release preparation
# 5. Other packages may be installed with apt-get.
# 6. If any of these things were used: Clean out sources.list,
# /var/cache/archives /var/lib/apt/lists, /etc/network/interface
# should be commented in again.
# 7. remove linux uml_* or just leave them.
# 8. run /etc/cron.daily/sysklogd & /etc/cron.weekly/sysklogd
# and clean out *.0, and dmesg if it needs it.
# 9. halt and mount filesystem on loop and remove .bash_history if you
# want to.
# 10. test again.
