DHCP client for Mac OS X

[Olivier Nicole]

Hi,

While the client is not fully related, it is talking to my serverthat
is ISC :)

OK, I do some dynamic DNS update and found out that in order for the
DNS to be updated, the DHCP client should send host-name parameter to
ISC DHCP server.

On linux and FreeBSD that is enough to set that in a
/etc/dhclient.conf file, but how to do the same with MacOS X?

TIA

Olivier
