AFAIK about System.map is it is not for recovery, but for
debugging. If kernel crashes, it tries get one to tell where it crashed,
give you backtrace and like that. It's easier to find the bug with it,
so unless you do not have a kernel that will ever crash, or you do not
want to send bug reports, you do not need one.
