is this a kernel you compiled during install or afterwards? once you boot into the livecd remember to mount your partitions and you should be able to copy the system.map from there.

Try
| Code: | mount $YOUR_ROOT_PARTITION /mnt/gentoo
mount $YOUR_BOOT_PARTITION /mnt/gentoo/boot
|
followed by
| Code: | | cd /mnt/gentoo/usr/src/linux |
or
| Code: | | ls /mnt/gentoo/usr/src/linux |
or
| Code: | | ls -l /mnt/gentoo/usr/src/linux/ |
Note the trailing slash.
Also, take a look at
later on to review the basic concept of a symbolic link.

are you sure you've mounted the partitions?

what kernel-sources did you emerge?

I think your simlink is pointing at the wrong dir |

Is this a new feature of Linux 2.6? System.map is not needed to boot a system on 2.4 kernels.

I believe that the system.map is for debugging purposes in case of a kernel oops, but I think your problem here is that your symlink is wrong.
what are the entire contents of your /usr/src folder? From your posts it sounds like it's just the symlink and no directorys?
| Code: |
mount /dev/hd?? /mnt/gentoo
cd /mnt/gentoo/usr/src
ls -l
|
what does that show? for example mine is:
| Code: |
nate@natescomp nate $ cd /usr/src
nate@natescomp src $ ls -l
total 5
lrwxrwxrwx 1 root root 30 Apr 16 08:44 linux -> /usr/src/linux-2.6.3-gentoo-r1
drwxr-xr-x 16 root root 808 Feb 1 11:44 linux-2.4.22-gentoo-r5
drwxr-xr-x 16 root root 624 Feb 19 06:15 linux-2.4.22-gentoo-r7
drwxr-xr-x 19 root root 1432 Apr 17 08:48 linux-2.6.3-gentoo-r1
drwxr-xr-x 18 root root 664 Mar 9 03:00 linux-2.6.3-gentoo-r2
nate@natescomp src $ |
I believe reading somewhere that there is a search path for system.map which includes /usr/src/linux/System.map as well as /boot/System.map; the reason the install guide says to copy it is that backups are good. I don't think it will keep the kernel from booting if it can't find it.
Hope that helps
