To make a long story short, I'm trying to remaster a Knoppix CD to make it into a Citrix thin client. I have just about everything working, the CD boots the PC, automatically logs in, and starts twm and the ICA Client. The only problem with the setup I have now is that the ICA Client configuration file is located on the CD, so if it changes in the future, I'd have to redo some of the remastering process and make new CDs for each thin client. What I'd like to do is be able to set the TFTP server option in DHCP, and then have the thin clients run a script at startup which reads this option and downloads the configuration file from the TFTP server. The problem is that I can't seem to find a way to get the value of that TFTP server option.

Knoppix uses pump as a dhcp client. I couldn't find a way to call it and have it return the value of a dhcp option. Anyone know of a way to accomplish this?
