WARNING: World writable directory /etc
uhm... that's not good...
You (or your admin) should change that. Since Unix will check the directory permissions first, it may be possible for you to clobber a file... example:
( I almost put in something to do with /etc/passwd or /etc/shadow, but decided against it... don't want to contribute TOO much to delinquency...)

Code:
$ cd /etc
$ cat > resolv.conf.me
#Haha! I'm so evul! Now you can't resolve anything!
^D
$ mv resolv.conf.me resolv.conf

Like I said above, anything in /etc or /var can be overwritten... That's bad news.

RESOLVCONF.CONF(5)					      System Manager's Manual						RESOLVCONF.CONF(5)

NAME
resolvconf.conf -- resolvconf configuration file DESCRIPTION
resolvconf.conf is the configuration file for resolvconf(8). The resolvconf.conf file is a shell script that is sourced by resolvconf(8), meaning that resolvconf.conf must contain valid shell commands. Listed below are the standard resolvconf.conf variables that may be set. After updating this file, you may wish to run resolvconf -u to apply the new configuration. RESOLVCONF OPTIONS
interface_order These interfaces will always be processed first. If unset, defaults to the following:- lo lo[0-9]* dynamic_order These interfaces will be processed next, unless they have a metric. If unset, defaults to the following:- tap[0-9]* tun[0-9]* ng[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]* search_domains Prepend search domains to the dynamically generated list. search_domains_append Append search domains to the dynamically generated list. name_servers Prepend name servers to the dynamically generated list. You should set this to 127.0.0.1 if you use a local name server other than libc. name_servers_append Append name servers to the dynamically generated list. private_interfaces These interfaces name servers will only be queried for the domains listed in their resolv.conf. Useful for VPN domains. This is equivalent to the resolvconf -p option. state_dir Override the default state directory of /var/run/resolvconf. This should not be changed once resolvconf is in use unless the old directory is copied to the new one. LIBC OPTIONS
The following variables affect resolv.conf(5) directly:- resolv_conf Defaults to /etc/resolv.conf if not set. resolv_conf_options A list of libc resolver options, as specified in resolv.conf(5). resolv_conf_passthrough When set to YES the latest resolv.conf is written to resolv_conf without any alteration. SUBSCRIBER OPTIONS
openresolv ships with subscribers for the name servers dnsmasq(8), named(8), pdnsd(8) and unbound(8). Each subscriber can create configura- tion files which should be included in in the subscribers main configuration file. dnsmasq_conf This file tells dnsmasq which nameservers to use for specific domains. dnsmasq_resolv This file tells dnsmasq which nameservers to use for global lookups. Example resolvconf.conf for dnsmasq: name_servers=127.0.0.1 dnsmasq_conf=/etc/dnsmasq-conf.conf dnsmasq_resolv=/etc/dnsmasq-resolv.conf Example dnsmasq.conf: listen-address=127.0.0.1 conf-file=/etc/dnsmasq-conf.conf resolv-file=/etc/dnsmasq-resolv.conf named_options Include this file in the named options block. This file tells named which nameservers to use for global lookups. named_zones Include this file in the named global scope, after the options block. This file tells named which nameservers to use for specific domains. Example resolvconf.conf for named: name_servers=127.0.0.1 named_options=/etc/named-options.conf named_zones=/etc/named-zones.conf Example named.conf: options { listen-on { 127.0.0.1; }; include /etc/named-options.conf; }; include /etc/named-zones.conf; pdnsd_conf This is the main pdnsd configuration file which we modify to add our forward domains to. If this variable is not set then we rely on the pdnsd configuration file setup to read pdnsd_resolv as documented below. pdnsd_resolv This file tells pdnsd about global nameservers. If this variable is not set then it's written to pdnsd_conf. Example resolvconf.conf for pdnsd: name_servers=127.0.0.1 pdnsd_conf=/etc/pdnsd.conf # pdnsd_resolv=/etc/pdnsd-resolv.conf Example pdnsd.conf: global { server_ip = 127.0.0.1; status_ctl = on; } server { # A server definition is required, even if emtpy. label="empty"; proxy_only=on; # file="/etc/pdnsd-resolv.conf"; } unbound_conf This file tells unbound about specific and global nameservers. Example resolvconf.conf for unbound: name_servers=127.0.0.1 unbound_conf=/etc/unbound-resolvconf.conf Example unbound.conf: include: /etc/unbound-resolvconf.conf SEE ALSO
