It does seem to be a flaw, but then again if a client that always uses DHCP has it's cable knocked loose because someone puts their foot under the desk in the wrong place, I guess this isn't so abnormal, but for laptop use it would be nice to have a "backoff-try-later/quit-now" toggle as a command line switch. FWIW for latptop use I set up a simple script to write a value to a file that controls my 'location', then put a case statement into rc.conf to read that value and only invoke dhclient when it's necessary. As long as I dont' push in the pcmcia card before I set the location setup, I don't see these messages and it's all very easy. Of course, now that I have a laptop with a built-in ethernet, that doesn't work anymore. Not even sure I have a good solution as of yet, but I bet it only requires pushing one layer into rc.network or something (as opposed to most linuces, which require following a trail of 12 scripts across 4 symlinks and hacking a system file (e.g. not rc.conf) to get the same effect) and the solution might even fit in rc.conf.
