In the boot, /etc/init.d/modules -Calucalting module dependencies-, I get the next error message: System.map not found - unable to check symbols /sbin/modules-update is run from /etc/init.d/modules, and at the end of that file is the next line: if [ -f /usr/src/linux/System.map ]; then depmod -a -F /usr/src/linux/System.map ${KV} else ewarn "System.map not found - unable to check symbols" fi /usr/src/linux/System.map -> That is the bug There are people as me that by security reasons unemerge kernel sources after of compile it and install it. So the option more secure is get it from boot (/boot/System.map) In addition if you use 'make install' (after of make && make modules_install) when you are installing kernel, System.map is copied in /boot Is necessary to check if /boot is in another partition for mounting it before of.
That file is damn useless for everyone except kernel hackers, must be some obsession or what... *** This bug has been marked as a duplicate of 104288 ***
