You have downloaded the patch from 2.2.18 to 2.2.19, and applied it to /usr/src/linux, where you had previously configured and built kernel 2.2.18. How would you avoid going through the entire configuration process again, and only configure options which are new to the patched kernel?
A. make oldconfig
B. make reconfigure
C. sh scripts/reconfig
D. Edit .config by hand
Correct Answer: A
Explanation/Reference:
Explanation: The ‘make oldconfig’ command will take the kernel config file named ".config" and only ask the configuration questions which are not already answered in that file. This will avoid having to go through the entire kernel configuration process again.
