# File:         adl-config
# Description:  ADL system configuration script
#               To run this script you must have the adl-config.src parameter
#               file located in root. It is important that the source parameter
#               file be read and understood before running the script.
#               See below for useful comments.
# Author:       Kevin Lister - kel@cup.hp.com
# Date          3.11.99
# Language:     Korn Shell

#
# Revision History
# 3.25.99 kel  Changed the name of the Clearcase install script in shell
#              archive, so it had to be changed here as well. Added an
#              eclipse install script to the shell archive, so a line to
#              to remove it if Clearcase is not installed had to be added
#              here as well.
# 4.1.99  kel  Added code to determine if the installed system is going to have
#              a graphics console. If yes, then the /etc/dt/config/Xservers
#              file needs to have the console server line uncommented.
#              Also added absolute paths to the unix commands.

#
# This script will configure a system to operate nicely in the ADL
# infrastructure. This script requires the adl-config.src file in order to
# run. The adl-config.src file contains variables that determine exactly
# what type of optional software to install, which patch bundle to install,
# configures various system files, etc.
#
# Here is a brief description of what this script will do:
#
#  1) Check that the script is run as root
#  2) Check that the architecture is correct. The script will run on most
#     hardware. The architecture is really only important when trying to
#     determine which 100Mbit drivers to install.
#  3) Sources the input parameter source file.
#  4) Determine if script is run intereactive or not.
#  5) Determine if 100Mbit drivers are to be installed
#  6) If intereactive, greet the user and display the parameter settings.
#  7) Modify the kernel system file located in /stand/system
#  8) Download the shell archive file from the anonymous ftp server and unpack.
#     The shell archive contains many files and symlinks and will not be
#     listed here. See the README in the ahell archive build area and the shell
#     archive itself for more details. One can also look through the "root"
#     directory that is used to build the archive to see which files and
#     symlinks are included.
#  9) Modify the /etc/rc.config.d files. (turn off unused stuff)
# 10) Modify the /etc/issue, /etc/gettydefs and /etc/motd files.
# 11) Modify miscellaneous files.
# 12) Perform miscellaneous setup procedures:
#     a) Run /net/bismol/App/admin/bin/setup
#     b) Run /usr/local/bin/ninstall -h bismol lp adm net3
#     c) Run /usr/adm/netdist/netdaemon.dy
#     d) Run /usr/sbin/catman -w
# 13) Set the system up for ClearCase installation upon automatic reboot.
# 14) Install optional software and patches from the specified depot server.
