Description Dmitry Tantsur 2016-10-20 11:55:17 EDT 
For quite some time I was wondering why we need "dhcp" in both introspection and deployment iPXE scripts. By this moment we obviously already have an IP address, so this just slows down everything.

However, today I've found an environment where this command is breaking introspection. It turns out that it uses the first NIC unconditionally, thus breaking fetching images from the second NIC.

I suggest removing this command.
