# PostInstall [devel] by Hans Eric Sandstrom (hes@xinit.se)
#
# The general idea is to run this script directly after a minimal
# installation. And then run it regularly when packages changes.
#
# This script:
# 1. Removes bloat that is installed even if you choose minimal configuration.
# 2. Installs your configured choice of packages using apt-get.
# 3. Deactivates unwanted but installed services.
#
# Currently I use two different configurations on my machines, hence
# the reason for a [devel] switch to this script.
# TODO: Check that all packages that is installed with the devel
# configuration is also removed when this script is executed later
# without the devel switch.
#
# With modifications this script probably works on other distributions
# but please browse thru it first so you understand what it does.
#
# Note: RedHat8.0 rpm has a very evil tendency to hang.
# If this script hangs on rpm, this is probably the problem.
# To fix this, kill all rpm processes (you'll probably have to use kill -9).
# Then do: cd /var/lib/rpm; rm __db*; rpm --rebuilddb. I don't know
# wether the script works for RedHat8 anymore since all my machines has
# been updated and I keep no apt repository for RedHat8. /hes20040208
#
# If you build your own packages you have to create a an apt-repository 
# for them and configure that repository into the sources.list file.
# Remember to put your own sources.list file in $SRCDIR/etc.
#
# Configure here
SRCDIR=/home/mailcore
ARCH=`uname -i`
# Catch 22, apt has to be present on a pristine machine
# Configure the path to your apt rpm here:
APTRPM=$SRCDIR/RPMS/$ARCH/apt-0.5.5cnc7-1.fr.$ARCH.rpm

# Put all installed services to be deactivated here
STOPSERVICES="rawdevices gpm"

# Put all installed services to be activated here
STARTSERVICES="named"

# Put all "bloat" rpms to be removed here. Some rpms are not installed
# on fedora and may later be removed from this list:
# gd gd-devel gnome-list imlib lilo lokkit mouseconfig ORbit
# redhat-config-mouse redhat-config-network-tui
# Suggestion: Drop vi and keep nano instead (save 7Mb)
