Although, I'm fine with tarballsfs ;-) No need to have this be a separate filesystem, we can use a binary sysfs file in /sys/kernel/ for this as the kernel is not doing any "parsing" of the data, it is just dumping it out to userspace. If I make /sys/kernel/config.gz be the same thing as /proc/config.gz will you fix up 'make localmodconfig' to use it? :) thanks, greg k-h
