Thanks for the pointers.

From my /etc/dhclient.conf:
interface "lagg0" {
send dhcp-lease-time 3600;
prepend domain-name-servers 127.0.0.1, 4.4.4.4, 8.8.8.8;
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers;
require subnet-mask, domain-name-servers;
}
And result is /etc/resolv.conf:
# Generated by resolvconf
nameserver 127.0.0.1
nameserver 4.4.4.4
nameserver 8.8.8.8
nameserver 192.168.1.1
True indeed this will work and I did have a look at dhclient.conf(5) to setup
the freebsd8:/etc/dhclient.conf. This will still call /sbin/dhclient-script
which will overwrite the configuration done to the /etc/resolv.conf each time
the system power is recycled. As per /usr/src/include/resolv.h, the MAXNS is by
default set to 3; which the default configuration user will not be aware of as
the entire focus will be on the ifconfig related flags in /etc/rc.conf. BTW,
the example indicated in dhclient.conf(5) has a typo which says
/etc/dhclient-script instead of /sbin/dhclient-script, indeed the system does
not fail if the typo exists in dhclient.conf.

There is simple solution: create file /etc/dhclient-enter-hooks
and override add_new_resolv_conf() there to do nothing:
add_new_resolv_conf() {
return 0

Works just fine for my systems.
Indeed this is a good suggestion, and this is if the user is aware of what to
look for and where in /sbin/dhclient-script it is documented.
A general sysadmin would be aware of /etc/nsswitch.conf and /etc/resolv.conf for
name resolution issues and I do not think they will be aware of so many possible
ways to handle the issue of resolv.conf getting overwritten by the usage of dhcp.
What would be the way out? Do you think it would be a good idea to push the
nameserver configuration information into /etc/rc.conf which happens to be the
single file that would handle the system configuration?
