What is considered a large dhcp load?

I'm expecting some of 512 users on that network and I'm not willing to
setup a different DHCP box.

My box has 1GB of ram. It would be nice if the RAMdisk size could be set
in configmode or something.

If the WebGUI does have enough options, though, and you like the ease of

access, you might hack the sources to mount a rw partition and write the

dhcpd lib directory there. You chould also just create a larger RAM 
disk. I'd be willing to hack up a custom image for the purpose, if you 
want it. Mounting a real rw partition, though, is an extremely bad idea 
if you use CF, since the dhcpd leases file changes so much.
