# Patch the configuration script. We need this to be able to run the
# script from outside the source directory as well. We're going to:
#
# 1) Change from relative to absolute the paths to the environment file
#    and the firewall executable.
# 2) Rename and change the path to the startup script, for consistency with
#    Slackware's init system.
# 3) Change the path to the unmodified copy of the config file, needed to
#    check for already existing setups.
# 4) Allow the script to be run correctly more than once, by removing
#    previously set values if no values are entered: this is to prevent,
#    for example, ports from remaining open, or NAT from remaining enabled.
# 5) Append the note, copied from the original install script and adapted
#    to the Slackware system, that users read when configuration is done:
#    this is mainly to inform that the "rc.firewall" symlink has to be
#    manually created in order to start up the firewall at boot-time. We
#    will NOT create the symlink automatically, as this should be done by
#    the system administrator.
