OK, that obviously wasn't necessary - I probably did it myself long ago. I've
used etherconf to reconfigure my network without any damage - but without fixing
things.

I changed that and things are still not right.
If I do "ifdown eth0", the firewall is torn down. If I do "ifup eth0" the
firewall is rebuilt. This is good. But if I remove/replace the pcmcia card,
ifup/ifdown don't appear to be run. The script as I have it (taken from a
reinstall, so not my fault :-) ) contains:
is_true $DHCLIENT || \
is_true $PUMP || is_true $BOOTP || is_true $DHCP || \
if [ -z "$IPADDR" -a -f /etc/network/interfaces ] ; then
INFO="Debian network setup"
start_fn () {
log /sbin/ifup $1
}
stop_fn () {
log /sbin/ifdown $1
}
fi
It seems I'd picked up a version of pcmcia-cs from sid in one of my experiments,
but even having downgraded this to 3.1.33-6 it does _not_ seem to invoke
ifup/ifdown (all that seems different is the use of hotplug in sid). I _did_
reset DHCP="y" when I recreated the network.opts file.
