Projects / Ksplice


Ksplice is practical technology for updating the Linux kernel without rebooting. It enables you to avoid the disruptive process of rebooting for kernel security updates and bugfixes. By making it easy to keep your systems up to date, Ksplice helps you avoid the security and stability risks of running out-of-date software.
