#!/bin/sh

# this script makes an attempt to build a proper set of rules
# for loading the DAHDI modules and automatically running dahdi_xcfg
#
# it accepts two parameters:
#   the root prefix to be used for finding/creating the files
#   the list of module names being installed
#
# the process is as follows:
#
# the file can be located at /etc/modprobe.conf (combined with all
# other rules), /etc/modprobe.d/dahdi (DAHDI only) or /etc/modules.d/dahdi
# (DAHDI only)
#
# when the file is DAHDI rules only, then we don't preserve the existing
# contents of the file; the system administrator can put desired options and
# overrides in a separate file with a name that appears earlier in the sort
# order, so there is no need to edit the file produced by this script
#
# when the file is combined with all other rules, then we make a backup
# of it and remove all the old DAHDI rules we can find, replacing them with
# new ones
#
# in addition, versions of module-init-tools 3.2.0 and later
# have the ability to pass module parameters specified on the modprobe command
# line to commands in 'install' rules, thus keeping them from being lost, so
# we try to determine what version is installed and take advantage of that
