$Id
# 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.  There are several ways to accomplish this:  
# Choose Edit->Stages->"user defined" and go one stage at a time, closing 
# the verbosity box with the slider bar between each stage, and then 
# reopen the verbosity box.  If the stage is particularly long, you 
# can toggle the slider bar to close the verbosity box and reopen it
# again clearing the buffer in the process.  You may choose a lower 
# verbosity level, or you may keep the verbosity box off altogether and
# look at /tmp/gbootroot_tmp'time-date'/verbose or 
# /tmp/gboot_non_root_`id -u`/verbose (normal user).

# --------------------------------------------------------------------
# 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.
