Generally, all Linux distributions needs a scheduled reboot once to stay up to date with important kernel security updates. RHN (or other distro vendors) provides Linux kernel security updates. You can apply kernel updates using yum command or apt-get command line options. After each upgrade you need to reboot the server. Ksplice service allows you to skip reboot step and apply hotfixes to kernel without rebooting the server. In this post, I will cover a quick installation of Ksplice for RHEL 5.x and try to find out if service is worth every penny.
