Thinking of it, no. This should / could be MI.

The use is for netbooting. At the moment on most machines the firmware
does dhcp / bootp to request IP parameters to load the boot loader. The
boot loader does a second dhcp / bootp to ask what kernel to load etc.
and the kernel in turn does a third dhcp / bootp to ask for its IP
parameters and root file system. If the boot loader can pass the boot
parameters to the kernel the entire dhcp / bootp stuff in the kernel can
be skiped. The kernel knows how to configure the network and can mount
NFS root without an additional dhcp / bootp.
