5 That will happen when when your /boot is on a separate partition: it
6 is not mounted (yet) when the kernel is looking for the System.map.

10 Neither. If you don't want it to complain, then copy the System.map
11 also to /boot when it is unmounted (or to /, that will do too).

15 No. Only when it oopses it will use the info to give a clearer
16 message.

21 Does ps need System.map? But if /boot is mounted during normal
22 operation, then it'll be able to find it. Maybe these programs
23 are even 'cleverer' and also have a look in /usr/src/linux/?
