5.3. Kernel installation
If you have made a native build on the box you wish to install, you can setup
the new kernel as follows:
within the kernel source tree linux/, as root execute:
[user@machine ~/dir]> cp vmlinux /boot/vmlinux-[kernelversion]
[user@machine ~/dir]> cp System.map /boot/System.map-[kernelversion]
[user@machine ~/dir]> cp .config /boot/config-[kernelversion]
|
Though it is not mandatory, we suggest you to replace
[kernelversion] by the version of the
kernel you built,
e.g.:
vmlinux-2.4.18-pa44. This will help you
dealing with multiple kernel versions on the same machine.
The same applies to
.config.
It is not needed to have a working kernel, though it might
be very helpful when configuring a new one.
Now, do
cd /boot, make sure that
vmlinux is a symbolic link to another
file, as in the following example:
[user@machine ~/dir]> ls -l vmlinux
lrwxrwxrwx 1 root root 35 Jun 23 01:38 vmlinux -> vmlinux-2.4.18-64-SMP
|
Make sure to remember the name of the kernel actually running
on your box if ever the new one won't work properly.
You are now able to ask
PALO to boot on it if needed
(see
Chapter 3 for more information).
Now do the following:
[user@machine ~/dir]> rm -f vmlinux
[user@machine ~/dir]> ln -s vmlinux-[kernelversion] vmlinux
[user@machine ~/dir]> sync
|
If you want to boot from network you can forget all this,
as you will need to set
PALO as explained in the
Section 3.3, and run
make palo
to create the bootable
lifimage.
If you have made a cross-compiled build or built a kernel on a
PA box which is not the one you wish to install,
you have to find a way to put vmlinux,
System.map and eventually .config
in /boot/ as mentioned before.
You can use the network (like ftp)
or a CD to do so, or even direct copy to the hard disk drive.
