It's my (current) understanding that -- at least, the way I have things set up for my laptop -- pccardd is responsible for dealing with recognizing when a card is present or not; since it isn't started until rather late in the sequence, the behavior you notice would appear to be reasonable under the circumstances. >... >Jun 16 18:35:42 3jane pccard[91]: pccardd started >After the cards are started the routes are added and reachable: As expected, yes. >BTW, I don't have an /etc/pccard.conf; I'm still using the default >/etc/defaults/pccard.conf.

Well, pccardd appears to get started out of /etc/rc.pccard, which gets sourced from /etc/rc (line 284, as of today's -STABLE). It would certainly be technically possible to start it (somewhat, at least) earlier, though I'm not convinced that's an approach to recommend. >The network's being unreachable at an earlier point would foil >Apache's or sendmail's startup if they were running on this machine >(and they just might be). Understood; since I maintain my copy of the CVS repository on my laptop, I also run Apache (for local cvsweb access). So what I do is this: * In /etc/rc.conf, I define the hostname as "localhost". * In the same file, I specify 'pccard_ifconfig="DHCP"' (& 'pccard_enable="YES"') * Created /etc/dhclient_exit_hooks, which I cobbled up so it gets control after dhclient has done what it normally would do, but just before it claims completion of its tasks. The code I cobbled checks to see if the current hostname is NULL or "localhost", and if so, and if an IP address was assigned, it does a "reverse lookup" of the IP address to determine what the hostname should be, and then sets it (the hostname). (I thought I had a copy of that script on the Web page I threw together about what I've been doing with the laptop, but I don't see it there. I'll try putting it up there shortly.) This basically works, though changing the hostname out from underneath X11 (which can happen if one wanders from one network to another -- especially easy if the NIC is wireless, as in my case) is pretty unfriendly. >Oddly, under 3.2 there were no such boot messages.

I confess I didn't really try using FreeBSD on a laptop until 4.x, so I don't have the background for that. Cheers, david -- David H.
