Hello,
Last time I tried to upgrade my kernel I botched it somehow. I would
like to upgrade from 2.4.20-gentoo-r7 to r8 and move my r7 .config
settings into the new r8 kernel. I used Genkernel to compile last time
and this time I would like to manually do this for learning experience.
I found the following on Gentoo web forum and just wanted someone to
take a look at this and tell me if this is outdated or still in its
correctedness. It also looks as though its missing some steps
concerning "System.map". Can someone please confirm the following
steps. And whether or not after step 11 I should "cp System.map" to
"/boot"
I also don't have anything referencing "bizImage" linux directory tree.
Maybe its because I used Genkernel last time?
I'm running a PIII 667EB coppermine processor.
*********************************
If you wish to maintain as much of your old kernel configuration as
possible when installing your new kernel, copy /usr/src/linux/.config
to your new kernel tree (1), then switch to the base source directory
(2) then delete the symlink pointing to linux (3) and re-link linux to
your new kernel tree (4), now enter your new linux directory (5) and
run make oldconfig (6) - this attempts to preserve existing kernel
configurations - you will be prompted to make choices regarding new
kernel options (and if you don't know whether or not to enable some
option, simply pressing <return> usually selects "No". Once you have
completed this step, then you should run make menuconfig (or make
xconfig) (7) and then carefully look over the sections involved in
selecting file systems, printer setup, usb setup and possible scsi
emulation-the time spent here can save much time and many needed
re-compiles later. After you have finished configuring the kernel, you
must compile and install your new kernel. (8-17) (in step format:)
[1] cp /usr/src/linux/.config /usr/src/linux-2.x.xx-yyyyyy/.config
[2] cd /usr/src
[3] rm linux
[4] ln -s linux-2.x.xx-yyyyyy linux
[5] cd /usr/src/linux
[6] make oldconfig
[7] make menuconfig or make xconfig
[8] make dep clean bzImage modules modules_install
**My Comments** shouldn't this be "make dep && make clean bizImage
modules modules_install" ??
And don't I wan't to "cd" to the new 2.4.20-gentoo-r8 kernel tree
before issuing this step 8 command?
[9] mount /boot (where /boot is an entry in your /etc/fstab, which
should [normally not be mounted during normal use)
[10] mv /boot/bzImage /boot/bzImage.old
[11] cp /usr/src/linux/arch/i386/boot/bzImage /boot/bzImage
[12] edit /boot/grub/menu.lst and add an entry for your new kernel and
replace the reference to bzImage in your previous kernel entry to point
to the deprecated kernel file (bzImage.old)
[13] if you are using nvidia- emerge nivdia-kernel
[14] if you are using alsa - emerge alsa-driver
[15] edit /etc/modules.autoload to reflect any changes in modules to be
auto loaded
[16] unmount /boot (ie. umount /boot)
[17] shutdown -hr now
and voila you new kernel entry should appear in the grub menu waiting
to be tried....
Thanks,
Joshua Banks
