dhclient.* files become net.* only after successful netboot

Somehow the final chunk of this patch isn't working.  Isn't that part 
supposed to happen only on the occasion where netroot is successfully 
mounted?  I seem to be missing something simple here...

Subject: [PATCH] dhclient.* files become net.* only after successful netboot.
 This is an attempt to avoid confusing post-boot scripts by having them
 consider only net.* files.
