Of course for all our customers that use ksplice and enjoy the cool zero downtime patching, theyt might not even have noticed if they ran *as many do* ksplice in automated mode or others just had to issue one single very simple command and they were done. No applications to bring down, no systems to reboot... and still safe, secure, patched, current.
some more specifics on the ksplice blog here.
There's also Time to release. The ksplice patch was available on Tuesday (5/14) while the RPM for the kernel was released on Thursday (5/16) by us and the other similar distributions. No hassle...
