System.map with several kernels?

jontamask · 05-22-2004, 07:27 AM

Hi,

I've just been thinking about the System.map file for a while. It's necessary to have a System.map that fits the kernel currently in use. But then: what i was thinking about is if you have several kernels to start linux from in lilo (e.g. after a kernel compile), is there any possibility to load different system.map files also?
Most of the times it shouldn't matter, I guess.

This question is written in pure interest!

Hi there, this link from Azmeen might be of help to you in answering your questions. "http://www.dirac.org/p/linux/system.map/".

i posted a similar question like yours but with the config file. you may want to check out the post. the above link is also included in that post too.

When loading the kernel named vmlinuz the system will look for a file named System.map. When loading a kernel named vmlinuz-custom it will look for System.map-custom. In other words each system.map should be named with the same suffix as the kernel and this way the system keeps everything straight. The config file in /boot is not used, just serves as a backup or convenient way to see what's enabled in the kernel.
