No, resolv.conf is only read once when the resolver routines initialize.
The solution is to run a local caching nameserver instance. You should do
this anyway, for performance reasons. Add 'named_enable="YES"' to
/etc/rc.conf, and modify your /etc/dhclient.conf as follows:
interface "ath0" {
supersede domain-name "orthanc.ca";
supersede domain-name-servers 127.0.0.1;
}
interface "bge0" {
supersede domain-name "orthanc.ca";
supersede domain-name-servers 127.0.0.1;
}
Change the domain string to something more appropriate, and adjust the
interface names to match your laptop. You'll need to start named and
restart the dhclient instances (in that order) for the changes to take
effect.
