System.map

[jAHu]

xem iba pridat do tejto diskusie, naco vlastne ten subor sluzi
kedze som to nevedel, a ani som ho pri kompilacii noveho kernelu nedaval a 
niekomu sa to tiez moze hodit
z tohoto popisu tiez vypliva ze okrem debugingu je mi na nic.

System.map is a file (produced via nm) containing symbol names and addresses 
of the linux kernel binary, vmlinux. 

Its primary use is in debugging. If a kernel "oops" message appears, the 
utility ksymoops can be used to decode the message into something useful for 
developers. ksymoops makes use of the System.map to map PC values to symbolic 
values. 

You may get warnings about your System.map being out of date. This won't 
affect normal running but its best to keep a copy around if there is a kernel 
bug / hardware failure. Note that ps l uses System.map to determine the WCHAN 
field (you can specify a map file with the PS_SYSTEM_MAP environment 
variable). The utilities look in a set of standard places for this file like 
/boot/System.map and /usr/src/linux/System.map
