Sounds cool.  Just remember to keep the size down.  (And if it looks like 
you're going to add more than about 50 bytes or so to the binary, thinking 
about adding a config option to make the new behavior compile-time 
selectable.  Some embedded systems don't have persistent storage in their 
writable filesystems, they lose everything on a reboot anyway...)

When you've got something for us to look at, send a standard diff -u patch to 
this list.  (The udhcp stuff is a bit weird because the maintainer of that 
applet also has it as an external standalone project, but keeping the two in 
sync is his problem...)
