Upgrading the kernel


I finally got a box setup to test stuff on, so I first wanted to try and upgrade my kernel version. I'm running RH 8 and it comes with 2.4.18. Is it normal to just upgrade the kernel itself? I'd rather not update anything else if possible. Thanks.

You can update the kernel by compiling a new one.

Go to www.kernel.org, download the source, and read the instructions within.

Make sure you include all your hardware in the kernel!

I've used RedHats up2date manager to update my kernel about 5 or 6 times now. I've never had a problem with it. It downloads and installs it for you automatically. Then when you reboot you will have the option to boot to your previous kernel or the updated kernel. If the new kernel does not work, for some reason, you can always revert back to your previous kernel.

Then you might have updated your kernel but you've never compiled it. Red Hat update complained loudly about my running a customized kernel and it never completed the update process.

Well, it did go into the source tree for my ``production'' kernel and delete various subdirectories (Documentation, etc. Worst of all it clobbered the include/linux directory. Nice.) Ended up having to fire up rpm and delete the updated kernel and reinstall the version I was using previously. And I suspect that the problems I've been having with xscreensaver (described in a posting under the Software forum) are related to Red Hat having a fit over my compiling a custom kernel. (I have no solid proof but the onset of the problems seem to correlate with the so-called `update'.)

On my RH7.x systems, I used to merely head over to the www.kernel.org site and download the new sources there. Just unpack the tar archive under /usr/src, redefine the symlink to point to the new sources, and compile as usual. Worked like a charm. You do have to be careful, though. There was at least one release (2.4.9 or .10 sounds familiar) that required some additional tools or somesuch to get that release to work correctly. Dunno the details. That may be a problem in a future release so it's worth watching out for.

AMDPwred: As for updating just the kernel: You can do that if you like. You might want to be watchful of any other updates that correct potential security problems.

Later,

Rick
