It does save us about 5% though, which is quite substantial when you're talking about fitting a kernel on a boot floppy. For the past few kernel versions it has made the difference between being able to base installation floppies on the standard Debian kernel (generic 486 flavor) or having to come up with radical new solutions. >>From my tests for this issue it looks like .26 has grown so much that we've now reached that point anyway though :-( Cheers, FJP
