small feature request

Would it possible to put a header on System.map indicating the kernel
version?
Sometimes my little brain forgets what kernel System.old is for.
Thanks, Garst

Just name it: System.map.2.4.16-xx (where xx is the build number)  This
is easy to automate in your install script.  Then real system map is "ln
-s"ed to the correct file.

If you have multiple kernels in /boot, name it System.map-2.x.xx-xxxx 
and let booting kernel decide on his own which map to take. No need for 
a symlink. If there's a /boot/System.map the kernel will ignore all the 
other maps.

It is on my list for kbuild 2.5, once I start on the new design for
reconciling kernel and modules.  Goodbye modversions, hello "something
that works" (I hope).

Yea Keith. Good luck.

Nooooo!!!!!

Don't break stuff by adding headers. There is already a version
in the file. It's in decimal, which sucks, but this will find it:

grep ' Version_' System.map

Adding a random 128-bit ID might be nice, as long as it's done
in the same sort of way and is available via /proc. Something
like this would do:  kern_128_id_UkZd1JLdOvAsALfFEL1UI

Strange, that is exactly what I was think of, adding symbols containing
information that tie the kernel, modules and System.map together more
reliably than the current "use some random System.map" method.

Do you want those exclamation marks back so they can be recycled?

That grep does not distinguish extra versions.
