>Description:
dhclient -q insists on printing stuff like:

New Network Number: 192.168.1.0
New Broadcast Address: 192.168.1.255

This makes the boot sequence output look pretty horrible. It also goes
against the man page, which says that -q should suppress all non-error
messages.

I think, however, that there are legitimate reasons for an ifconfig.int
script to generate output. If so (and assuming we agree that it is worth
making the boot output look decent), there are three obvious solutions:

(1) Put every interface on it's own line. e.g.:

Bringing up ath0:
[Hello, I'm a noisy interface.]
Bringing up bge0:

Simple, straightforward, but not particularly nice.

(2) Have a flag in the first line of an ifconfig.int script like so:

#NOISY
dhclient $int

e.g.:

Bringing up ath0:
[Helloo, I'm a noisy interface.]
Bringing up interfaces: bge0.

Fairly simple, but rather inconsistant.

(3) Get rid of the "all on one line" method altogether:

Redirect the script output to somewhere in /tmp. Then, based on whether
the file is empty or not, and the exit status of the script, use the 
appropriate format: 

[Assuming no -q flag to dhclient]

Bringing up ath0: OK.

 I'm sorry, but I fail to see how two lines of, IMHO, vital INFORMATION for 
 each configured network device can be described as noisy, especially when 
 considering that it conveys important network configuration stats.

 Those who don't like it may try to redirect output to the /dev/null device.

 Did you actually read the PR?

 You've completely missed the point. It is, as you yourself say, 
 "INFORMATION," not an error. Therefore it contradicts the man page
 specification.

 But then they won't see error messages!
