Well, for example, a kernel update might be due to some new severe security exploit, and the old kernel might be vulnerable to it. Running an old kernel on an Internet-facing system might then be a Bad Idea(tm). In theory, for each kernel update you could look at the changelog to see what was actually updated and why, and then decide if you need to run the updated kernel or not. But most people typically don't want to invest the time and effort to do that, if it's easier to just reboot the system. These things should be decided on a case-by-case basis. :-) HTH, :-) Marko -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Most of the time, I recompile when a new stable rc hits kernel.org. Quite often, the rc doesn't differ from the release, or it differs in parts which doesn't affect me.

Though updates to stable kernels are often security or data loss bugs, so staying on the old kernels without reviewing the changes isn't a great idea. And reviewing the changes would also take time and expertise. So for most people just rebooting at the first covenient time is going to make the most sense. You might want to keep an eye on the kGraft project. https://www.suse.com/communities/conversations/kgraft-live-kernel-patching/ https://www.suse.com/company/press/2014/1/suse-develops-kgraft-for-live-patching-of-linux-kernel.html And Red Hat has a similar project: http://rhelblog.redhat.com/2014/02/26/kpatch/ -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Unlike some other distros, Fedora tracks the upstream kernel versions quite closely, but there's nothing obliging you to always use the latest kernel if it doesn't fix anything relevant to you. poc -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
