Centos kernel installation without restart
 

Hi

If i install a new kernel using yum update and i don't reboot and then after a few days i install again using yum update a newer kernel and then i reboot it will auto load the latest one?

Thanks

reboot
that is right now the ONLY option

It will load the latest one by default.

You ALSO get, by default, the latest 3 kernel versions.

The main reason to reboot after installing a kernel, is to know if it works with your system.

It would really suck if you did three or four updates with new kernels, then had to reboot only to find that none of them worked...

My habit is to keep the original one that worked around - and allow the system to continue updating. Then if none of the current kernels work, I still have the original one that DID.

And occasionally, manually replace that backup kernel with one that also works.
