#! /bin/sh # postinst.skeleton # Skeleton maintainer script showing all the possible cases. # Written by Charles Briscoe-Smith, March-June 1998. Public Domain. # Abort if any command returns an error value set -e # This script is called as the last step of the installation of the # package. All the package's files are in place, dpkg has already done # its automatic conffile handling, and all the packages we depend of # are already fully installed and configured. # The following idempotent stuff doesn't generally need protecting # against being run in the abort-* cases. # Install info files into the dir file : install-info --quiet --section "section pattern" "Section Title" \ : --description="Name of the document" /usr/info/foo.info # Create stub directories under /usr/local : if test ! -d /usr/local/lib/foo; then : if test ! -d /usr/local/lib; then : if mkdir /usr/local/lib; then : chown root.staff /usr/local/lib || true : chmod 2775 /usr/local/lib || true : fi : fi : if mkdir /usr/local/lib/foo; then : chown root.staff /usr/local/lib/foo || true : chmod 2775 /usr/local/lib/foo || true : fi : fi # Ensure the menu system is updated : [ ! -x /usr/bin/update-menus ] || /usr/bin/update-menus # Arrange for a daemon to be started at system boot time : update-rc.d foo default >/dev/null case "$1" in configure) # Configure this package.
