[gentoo-user] system.map file in /boot. How to manage?

[Dale]

Howdy,

The subject line pretty much describes this.  How does one manage the
system.map file in /boot?  Is it needed?  Should it be updated with each
kernel?  I tend to keep 2 to 3 kernels installed.  I tend to keep 2 that
I know are stable and one testing.  After a while, I may remove the
oldest one and only have two, just in case.  Should I version the
system.map file the same as kernels?  Does just one with no version get
the job done?  Update the file with each kernel upgrade or install one
and done?

While at it, what does it even do?  If it needs it, it doesn't matter
but just curious. 

Thanks for any tips on this.
