Yeah, I turned off the config option and compared the sizes. Now, both
result in the same build size. Thanks for the suggestion Greg. Still, my
concern is that the distro's build is generating a small build size in
spite of having the option 'CONFIG_DEBUG_INFO' set to 'y'. Any thoughts?
Well, the distribution is for sure building the debug info. But later on, they strip out the debug info and creates a 2nd kernel package (and 2nd packages for all modules) with the debug info. Thus, the regular kernel image and modules appears as stripped ones on your system.
Cheers,
