Static leases with personalized parameters for each one (LTSP and PXE Booting)

[chronos00]

Hi everyone,

I have an LTSP Ubuntu server, ofering a TFTP and several images for booting through PXE. I can configure pfSense to direct every DHCP client to this server, and to ONE of this images.
The problem is that several thin-clients have particular configurations, hence particular boot images. I need some way to configure the static DHCP leases to point to different boot images in the server.

I have seen this thread with similar problems, but not quite this one.

Or this two threads where they need particular configurations for static leases, but had no answer:
http://forum.pfsense.org/index.php/topic,16461.msg86074.html#msg86074
http://forum.pfsense.org/index.php/topic,24573.msg127114.html#msg127114

Since it has been quite a while since those threads had any activity, I considered It would be rude to revive them.

Perhaps there is a package add-on to install some other DHCPd which has the options I need?
I am using pfSense-2.0-BETA1-20100510-1132

Thank you in advance!
