Wasn't able to find further info on this. Two questions about Ksplice:
This page says "CloudLinux with Ksplice Uptrack can be purchased from Cloud Linux. Ksplice Uptrack is also available for existing CloudLinux customers from the Ksplice Web site, at www.ksplice.com."
Seems to be missing from the ksplice site since Oracle purchased them. Is this still available from CloudLinux?
Also, from an earlier post Igor mentioned: "Please, note that ksplice updates only security bug fixes, new features (that we sometimes add) are not included in ksplice updates."
So, kernel updates with new CloudLinux features still require a reboot?
