This message is being issued by /sbin/module-update. It is called from /etc/init.d/modules to update /etc/modules.conf. It's complaining because /boot has not been mounted yet. As far as I can tell, /boot is treated no differently than any other non-root filesystem.

Unless it has changed recently, the system I just installed last month

I considered opening a bug, but it wasn't that important and I never really
got around to it.
A kludgy temporary fix would be:
# mount -o bind /dev/rootdev /mnt
# mkdir -p /mnt/usr/src/linux
# cp /usr/src/linux/System.map /mnt/usr/src/linux
# umount /mnt

de Almeida, Valmor F. wrote: Hello list, Following closely the instrunctions on the Gentoo Linux x86 Handbook, I installed gentoo recently (info below) and just did the first reboot before finalizing the installation. All worked except for this message during boot System.map not found - unable to check symbols. Well I had the same problem some time before. I'm using ~x86 tree and after a update it was solved. I don't remember which package was causing the problem. But I'm sure it's some init script. It's not a kernel problem. I now have no problems. But here's my logic as to why this warning shows up. According to /etc/fstab, /boot partition does not get auto mounted during boot up, so the init script can't find /boot/System.map (/boot being the folder, an empty on in /) which doesn't seem to cause problems during/after booting (??). Don't worry.. It wont cause no harm, except for the annoying warning.. I did a manual kernel compilation and the handbook didn't say anything about copying System.map to /boot. On a second attempt to reboot I did copied System.map to /boot. My grub.conf follows below. In /boot I have System.map and System.map-2.6.15.1 files (System.map is a soft link). To make the warning disappear, simply copy /usr/src/linux/System.map to /boot (don't mount the boot partition, i.e., make sure hda1 is *NOT* mounted).. This should hopefully make the warning disappear.

That will happen when when your /boot is on a separate partition: it is not mounted (yet) when the kernel is looking for the System.map. 1. Is this a vanilla or gentoo kernel specific issue? Neither. If you don't want it to complain, then copy the System.map also to /boot when it is unmounted (or to /, that will do too). 2. Does the kernel itself actually need the file? No. Only when it oopses it will use the info to give a clearer message. 3. Are programs like ps able to find the file themselves as they seem to work? Does ps need System.map? But if /boot is mounted during normal operation, then it'll be able to find it. Maybe these programs are even 'cleverer' and also have a look in /usr/src/linux/?
