proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+#!/bin/bash
+# Copyright 2006 Gentoo Foundation
+# Distributed under the terms of the GNU General Public License v2
+
+# /etc/pdnsd/pdnsd.conf updater
+# Written by Oldrich Jedlicka (oldium.pro@seznam.cz)
+
+# Implementation notes:
+# * The assumptions are same as for other scripts like bind and dnsmasq:
+#   - We assume that we are a local dns cache - after all, why would a server
+#     use resolvconf?
+#   - Now that we have assumed this, we also assume that generic DHCP clients
+#     will enter their domains and search domains ONLY in the "search" field
+#     in their resolv.confs and VPN clients will put the domain they are for
+#     into the domain field only.
+#   - This allows pdnsd to forward domains for a specific VPN domain to the
+#     VPN nameserver and everything else to the standard name servers.
+#
+# HOW-TO CONFIGURE:
+#
+# To get this working, you need to do only two steps
+#
+# 1. Create a basic configuration of /etc/pdnsd/pdnsd.conf, you can use
+#    /etc/pdnsd/pdnsd.conf.example to start.
+#
+#    Additional configuration will be created automatically be resolvconf.
+#    The generated server sections has labels starting with "resolvconf", so
+#
+#        DO NOT USE "resolvconf" IN YOUR LABELS!
+#
+#    Check if the status_ctl is set to "on", otherwise the configuration
+#    will not be automatically reloaded - see sample config file.
+#
+#    You are free to edit automatically created server sections, but always
+#    write one option per line. There are few options that are always recreated
+#    and your changes in them will be lost. Here is the list (with example
+#    values):
+#
+#        preset=on;
+#        ip="192.168.0.1","192.168.0.2";
+#        include=".net",".com";'
+#
+#    The exclude directive in "resolvconf" server section is partly recreated.
+#    Known (configured) domains in the form ".<domain>" or ".<domain>." are
+#    added and removed automatically, unknown domains (also those not in 
+#    the format above) found in this directive are kept.
+#
+#    The sample configuration file /etc/pdnsd/pdnsd.conf prepared to work
+#    with resolvconf would look like this:
+#
+#global {
+#	perm_cache=2048;
+#	run_as="pdnsd";
+#	status_ctl = on;   # Important to enable status control
+#	run_ipv4=on;
+#	par_queries=2;     # How many servers are probed in parallel
+#	interface = "lo";  # Interface on which the pdnsd listens
+#}
+#
+# 2. The last step is to configure dns configuration for /etc/resolv.conf
+#    for the lo interface. In Gentoo we set it up like so in /etc/conf.d/net
+#
+#      dns_servers_lo=( "127.0.0.1" )
+
+# pdnsd config file
+PDNSDCONFIG="/etc/pdnsd/pdnsd.conf"

+# Backup suffix
+BACKUPSUFFIX=".backup"
