/etc/resolv.conf changed in Snow Leopard?

[Hal Itosis]

The contents of /etc/resolv.conf (or rather the target file /var/run/resolv.conf) seems to have some commentary now in Snow Leopard (which wasn't present in 10.5.x):

$ vis /var/run/resolv.conf
#
# Mac OS X Notice
#
# This file is not used by the host name and address resolution
# or the DNS query routing mechanisms used by most processes on
# this Mac OS X system.
#
# This file is automatically generated.
#
domain myipprovider.net
nameserver 123.45.67.89
nameserver 123.45.67.90

I find the word "not" there a bit puzzling. [i.e., what does this message mean?]

Is there a newer method (or an old one unbeknownst to me) to discover our DNS servers on 10.6.x client?

I also ask this because i've found a thread where the symlink /etc/resolv.conf has been replaced by an actual file. Isn't that possibly a cause for alarm... or is this the new norm?
