One extreme workaround is to use the OpenBSD port of ISC dhcpd 3.1.0
(in the 4.3 ports repository )
If you do, you can declare custom option values symbolically, like this:
option openbsd-install-script code 225 = text ;
and then later:
option openbsd-install-script
"http://www/config/custom-install.sh";;
You also need to make sure that your dhcp client is requesting the
option values you care about, see /etc/dhclient.conf
In a recent email to [EMAIL PROTECTED], Nick Bender stated:
Note that if you use the stock dhcpd you need to be running a version
built
after 10-sep-2008 as there was a bug in dhcpd which caused unreliable
handling
of dhcp option numbers greater than 63.
So this might be related to your problem as well.

Hi,
I got a new machine to become my new server, so I installed OpenBSD
4.3
stable and all services thar run on the old machine.
The older one runs OpenBSD 4.2 stable upgraded from OpenBSD 4.1
stable,
everything works fine including dhcpd that pass some special options
that
says to System Imager Client which server to search for.
On the new machine with the same configuration file, it does not
work. The
System Imager clients did not get the values, I think it is not
passed. All
the default information are passed.
I recompiled again my userland to try to solve this, but it not works.
Below my configuration file:

(Other clients)

Any idea , how to solve this?
Thanks in advance.
