适用于openSUSE的update-resolv-conf

I didn't find the `resolvconf' package on openSUSE. In fact, openSUSE uses `netconfig'. [1] provides a snippet claimed to be working on openSUSE, but it failed to replace the DNS nameservers on my computer. I edited the `update-resolv-conf' file to suit my needs, and I omitted the `DOMAIN' part.

The following script is available on https://gist.github.com/1675504

#!/bin/bash
#
# Parses DHCP options from openvpn to update resolv.conf
# To use set as 'up' and 'down' script in your openvpn *.conf:
# up /etc/openvpn/update-resolv-conf
# down /etc/openvpn/update-resolv-conf
#
# Used snippets of resolvconf script by Thomas Hood <jdthood@yahoo.co.uk>
# and Chris Hanson

#
# Adjusted for openSUSE and its 'netconfig' component
# using dirty tricks by multiple1902.
# Omitted the 'DOMAIN' part.

# Example envs set from openvpn:
# foreign_option_1='dhcp-option DNS 193.43.27.132'
# foreign_option_2='dhcp-option DNS 193.43.27.133'
# foreign_option_3='dhcp-option DOMAIN be.bnc.ch'
