Hi what do you install when you want to update kernel?
I only think it's kernel-devel and kernel
but what is as well necessary so it works well?
(btw. I update kernel with yum on fedora core4)

basically just the kernel and its modules...

upgrading the -devel package shouldn't hurt, though, as long as your distributor is recommending that you upgrade it... same for the source...

and how to update its modules? I don't really understand the word.. I know there is a module for my internet and for my music card and stuff so do you mean I should update my hardware modules?

usually there's a package called kernel-modules which includes the kernel modules... yes, the modules are the drivers for your hardware which weren't built into the kernel... i'm sorry i can't give you a precise answer as i don't use fedora so i'm not sure how they package their kernel packages... on slackware there's basically four kernel packages: kernel-ide, kernel-modules, kernel-headers, and kernel-source...

my guess is that your kernel-devel package is the kernel headers...

what kernel packages are you getting prompted to update?? your best bet is to only update those that you are being prompted for... i mean, that's kinda the point of having one of those automated package managers, right?? like, to let it make these kinda decisions for you??

yes indeed, only I had some trouble last time I updated kernel with yum -y update kernel (I couldn't boot in init 5 because rhgb screen crashed and selinux didn't let my use internet) so I was wondering what I did wrong

Did you read the tutorials? Check out http://www.linuxquestions.org/linux/...Fedora_Systems

That should get you well on your way.

he's not recompiling his kernel, he's just updating kernel packages with yum...
