we trying to secure our network boot environment with UEFI secure boot. 
Because of that we put kernel, initrd and cmdlin in one big file with objcopy. 
Therefore we can't use ipxe for dynamically fill up some cmdline parameter, 
for example ip=${net0/ip}

Is there a way to write the value of ip=${net0/ip} in a UEFI variable, 
so that during boot the client don't have to do another DHCP handshake?
