Hi Yinghai, sorry for delayed response. I like the idea much since it'll allow
to log decompressor messages in case if someone would be changing exitsting code
or developing new one, though this touches boot protocol so that grub/syslinux
and friends will have to update their code as well which of course need some
time.
