Initial Package Version: 4.2.4-P1
Upstream Status: Rejected by upstream.
Origin: Based on Debian's dhclient-script, but modified for BLFS
Description: This patch replaces original linux script for dhcp client with
better one which is based on Debian's dhclient-script, but modified
to be used on LFS/BLFS. It also removes net-tools dependency.

# dhclient-script for Linux. Dan Halbert, March, 1997.
# Updated for Linux 2.[12] by Brian J. Murrell, January 1999.
-# No guarantees about this. I'm a novice at the details of Linux
-# networking.
-
-# Notes:
-
-# 0. This script is based on the netbsd script supplied with dhcp-970306.
-
-# 1. ifconfig down apparently deletes all relevant routes and flushes
-# the arp cache, so this doesn't need to be done explicitly.
-
-# 2. The alias address handling here has not been tested AT ALL.
-# I'm just going by the doc of modern Linux ip aliasing, which uses
-# notations like eth0:0, eth0:1, for each alias.
+# Modified for Debian. Matt Zimmerman and Eloy Paris, December 2003
+# Modified to remove useless tests for antiquated kernel versions that
+# this doesn't even work with anyway, and introduces a dependency on /usr
+# being mounted, which causes cosmetic errors on hosts that NFS mount /usr
+# Andrew Pollock, February 2005
+# Modified to work on point-to-point links. Andrew Pollock, June 2005
+# Modified to support passing the parameters called with to the hooks. Andrew Pollock, November 2005
+# Modified to use the script with Linux From Scratch by Armin K., May 2012
-# 3. I have to calculate the network address, and calculate the broadcast
-# address if it is not supplied. This might be much more easily done
-# by the dhclient C code, and passed on.
-
-# 4. TIMEOUT not tested. ping has a flag I don't know, and I'm suspicious
-# of the $1 in its args.
-
-# 'ip' just looks too weird. /sbin/ip looks less weird.
-ip=/sbin/ip
+# The alias handling in here probably still sucks. -mdz
+# update /etc/resolv.conf based on received values
