Did you know you don't need a DHCP client?

you can use the kernel autoconfiguration to setup your network working, just add ip=dhcp.

Are there any particular kernel modules needed for that?

Nope, you can use the netboot hint to see all the options required http://documents.jg555.com/netboot

Jim Gifford is the person I have to credit for this tidbit of information.
someone was discussing the lack of dhcp client software in the linux from scratch sources.
in a discussion on the lack of an http client tool to download packages with to add more software on an lfs system.
[ ftp is supported for this purpose, but you have to stop and think to realise it ;) ]

reading the lfs-help email list, I find interesting little features in linux like this. :)

Still, if it works in your environment for your DHCP requirements, then it must be robust enough to use. The only potential problem is if someone else comes in to diagnose a DHCP problem and doesn't see a DHCP script they will misdiagnose the cause of the problem.

Too bad, though. :D

I'm all static ips, so I don't use it myself.
If someone with a small network needs to use it for a low end system that isn't resource rich then it's a handy tool option, if you are doung thin client networking then it's a useful tool.

after all, you can't use tftp to transfer the boot files if you don't have an ip address :D

The funny thing is that LFS is designed as a tool to let you learn more about the os, yet it's never mentioned in any linux courses.
