make config and .config file
What's the situation with the .config file when recompiling the kernel?
I am running 2.6.12 and it took me a few attempts to get that config
right, which I stupidly didn't document.
Now I want to upgrade to 2.6.16 and I am not sure whether I can use the
old .config file from my /usr/src/linux-2.6.12 dir.
Will using an old .config from 2.6.12 override some new defaults that
may have appeared in 2.6.16?
I'm unsure of the mechanism used by the make xconfig or menuconfig step.
