That's not a nice place. Besides the fact that System.map is
neither library nor module, /lib/modules is less likely to
exist than /boot is. It's a wee bit slower too.

The System.map file contains info related only to the main kernel
image, and nothing related to modules. So this is better:

/boot/System.map-2.4.18-pre1
/boot/vmlinuz-2.4.18-pre1
/boot/bzImage-2.4.18-pre1
/boot/config-2.4.18-pre1

(losing the foul '.' on the .config file)
