# This script generates a .tar.gz archive which contains
# "configuration.txt" -> includes system information (hostname, uptime, ...)
# most of the important configuration files
#
# The archive file should contain most everything needed to repair or re-install
# a standard Linux or Solaris system
#
# This script has been tested with Redhat 7.x and Solaris 8
#
# Feel free to extended this script - but please send your extensions to
# ingmar.koecher@netikus.net - so that others can benefit as well.
