   There is? I don't recall discussing that at all, and if we do eventually go
the ELF way, I think the kernel would be one of the last areas we'd want to
convert since it further complicates our cramped bootblocks.
   The only issue I have against ELF is that I'm concerned that the overhead
for processing the much more sophisticated header at exec time might have a
serious impact on exec performance (something I'm particularly sensitive to
since I wrote the a.out exec code for FreeBSD).
