Also in the way of usage/documentation, I'd propose updating the man
page to the following to reflect the actual behavior of the -n flag:
Original:
The DHCP client can be directed not to attempt to configure any
interfaces using the -n flag. This is most likely to be useful in
combination with the -w flag.
Proposed:
The DHCP client can be directed not to attempt to configure any
interfaces using the -n flag. This is most likely to be useful in
combination with the -w flag. If -n is specified as an argument, do not
list any interfaces (if0...ifN arguments).
The actual behavior seems to be that dhclient will error at
initialization if -n and an iface name (eth0) are passed at the same
time. Upon reading the man page the first time, I assumed that -n would
simply not ifup/ifdown the interface. Testing revealed that to be an
incorrect assumption, obviously. :-)
