Difference between System.map and /proc/kallsyms

[Jamal]

Hi..

After reading Documentation on System.map, i understood that , whenever 
an oops happens the following addresses  will be converted to its 
function name by klogd daemon using System.map.

Now when we have /proc/kallsyms which stores the symbol table in the 
kernel image itself.Then what is the need of System.map file??Is any 
process or daemon still using it??
