Re: boot-time kernel selection and /System.map mismatch
Yes. Not just Lilo, but loadlin, chos, GRUB, etc. The idea here
is that it is very nice to have a bunch of kernels around to choose from.
For instance, when I am doing kernel hacking, I need to be able to boot
from my testing kernel, and still have a stable kernel lying around for
when the testing kernel crashes. It is also nice to be able to boot
from stable (2.0.X) and several of the latest unstable kernels to try
out new stuff. Debian does not support this kind of thing well at the
moment, which is why I currently completly bypass Debian kernel packaging
support. If Debian installed kernels as
/boot/linux-2.0.30
/boot/system.map-2.0.30
/boot/linux-2.1.47
/boot/system.map-2.1.47
etc. and then behaved correctly by symlinking /system.map and /vmlinux
on boot with something like:
ln -s /boot/linux-`uname -r` /vmlinuz
and
ln -s /boot/system.map-`uname -r` /system.map
(This was done without checking corectness, so I might have done those
wrong.) This sort of thing would be _much_ friendlier to the
multiple kernel using crowd (like me), who want to select one of
many different kernels on boot up.
