Add a kernel tag
Does /proc/config.gz always contain all supported options of a kernel?
Assuming I have a running Linux system that has the /proc/config.gz file: Does the (unpacked) file always contain all of the options the particular kernel supports, including commented out like: `#CONFIG_SOMETHING is not set` or is it possible that some options which the kernel supports do not appear at all in that file? (the usefulness of knowing that for sure is to, perhaps, be able to do some problem hunting without currently having access to the buildroot config files that were used to create the Linux image at hand)
