No, I don't think DHCP was involved and it did not work as painless as it should have. I was thinking that DHCP might provide an address to a portal or such that might do the actual work. A bit like the "next server" for TFTP.


Okay, so just to be clear here, I'm not looking for new applications for DHCP.

Right, that is fine.

   I'm asking people to tell me if they disagree with my theory that services of this type (a) can't be generally configured by DHCP and (b) aren't typically configured by DHCP at the present time.   Yes, of course you can cobble together some hack using DHCP.

The question is (a) is it _ever_ a good idea, (b) is it safe to enable this behavior by default on all nodes, and (c) if it's not safe, is the behavior in any sense useful?

I tend to look at this from the opposite side, what are the services that need to be configured and infomation that needs to be delivered? And as a consequence what are the tools?
What is in the toolbox now and what is missing? Some of the missing tools are leading to ugly hacks now.
The answer might not be DHCP, but then what is it?

I am still trying to learn more.
