different kernels use the same boot.b?

Dear all,

When I compiled the kernel, I should copy the System.map to the /boot directory.

Normally, some books teach us the delete the old System.map file,
But, did the "old" kernel need to use the "old" System.map? Would the new System.map casue error for old kernel?

well ususally the system.map file is in the format like System.map-x.x.x where the x's are the version number...
so when you recompile all you should do is remove the symlink from system.map-x.x.x --> system.map and then make a new symlink to point your new system.map-x.x.x. to point to system.map...

Then, would the new System.map cause error to the old kerenl?

well i don't have a definite answer for that, but what i can say is that it makes it a definite answer in my mind for the only reason of the following question: why would this step even exist if it didn't matter? thats the way i look at it...so i would have to say yes it would cause an error.
