+Ksplice allows system administrators to apply patches to their
+operating system kernels without rebooting. Unlike previous hot
+update systems, Ksplice operates at the object code layer, which
+allows Ksplice to transform many traditional source code patches into
+hot updates with little or no programmer involvement. In the common
+case that a patch does not change the semantics of persistent data
+structures, Ksplice can create a hot update without a programmer
+writing any new code.
