... and you can't go use etherboot or whatever, you have to deal with it. 
You can deal with it today because ipconfig is small, you might not be 
able to deal with it tomorrow if you'll have to transfer twice as much 
because of a big initrd.

But that's exactly my point. The ipconfig functionality is needed and what 
I ask for is that whatever means (if any) are chosen to replace it, they 
should keep the low size.

I do not doubt this, but I'm afraid that you (or we) might not be able to 
do it again tomorrow. And probably this is an ideal case where you have 
used the better solution as client (etherboot)...
