3# This example script retrieves the DHCP state of a given interface.
4# In the interest of keeping the KVP daemon code free of distro specific
5# information; the kvp daemon code invokes this external script to gather
6# DHCP setting for the specific interface.
7#
8# Input: Name of the interface
9#
10# Output: The script prints the string "Enabled" to stdout to indicate
11#	that DHCP is enabled on the interface. If DHCP is not enabled,
12#	the script prints the string "Disabled" to stdout.
13#
14# Each Distro is expected to implement this script in a distro specific
15# fashion. For instance on Distros that ship with Network Manager enabled,
16# this script can be based on the Network Manager APIs for retrieving DHCP
17# information.
