Change from stock 2.4 kernel to 2.6 kernel

jrbush82 · 02-10-2006, 12:13 PM

I'm wanting to try out building a "Linux From Scratch" system, and it is recommending I use kernel version 2.6.2 or later. I used the default 2.4 kernel that came with Slack 10.2. Is there an easy way to switch from the 2.4.31 kernel to the 2.6.31 kernel that is on my CDs without having to recompile a new kernel all together?

Thanks

Hi,

On the Slackware CD under /extra or when downloading slackware-current you'll find a standard 2.6 kernel that functions with similar functionality on most systems. Having said that, if you plan to build your own system almost from scratch, I highly recommend building your own custom kernel for your hardware.

By the way - if you want to build Linux From Scratch I recommend checking the LFS forum here...

slackware/current/testing (as of today, 20060210) has

kernel-generic-2.6.14.6-i486-1 and
kernel-modules-2.6.14.6-i486-1

get both of those packages and installpkg them,

check your lilo.conf, run lilo, reboot, choose 2.6 kernel.

optionally, also get kernel-source-2.6.14.6-noarch-1, for
when you do want to compile a kernel, or just get
2.6.15.4 source from kernel.org

HTH,

HTH,

Thats the information I was looking for. I didn't know if just installing the package would do everything for me, or if I had to then put the bzImage into /boot modify lilo.conf etc... been a long while since I've been into linux and before lots of things were much more manual than now... Thanks for the info.

I don't know off the top of my head what the doinst.sh in the kernel package does.
I am confident it puts the kernel in /boot, and it may update your lilo.conf,
but as a general rule I always *check* lilo.conf and run lilo whenever I fiddle
with kernels.

Installing the Slackware module and kernel packages will install and set up all the links ready to boot.

The only little problem I find with this is that Lilo does not then give the option of booting either 2.6 or the original 2.4 kernel. In any case the old kernel is not removed by the installation.

I prefer the install the kernel to /boot manually without using symlinks and then edit and run Lilo to set up the multibooting.

Is there a 2.6 kernel with built in Reiser 3? My whole system is ReiserFS it is too late to install a module
