Where can I find Terms of Service for TuxCare Live Patching Services?

What do you mean by "no reboot or service restart" needed?

Live patching technology means that the faulty or vulnerable code gets corrected while it is resident in memory, during software execution. This means that an instance of the kernel (in the case of KernelCare Enterprise), or a shared library (in the case of LibraryCare), gets the corrected behaviour as it is running rather than only after the code is unloaded and loaded again. This means that you don't have to stop the system and restart it (when the affected code is part of the kernel) or stop and start the service to pick up the fixed code. No downtime for your end-users or computing load.

How long until the patches are delivered to a system running TuxCare Live Patching Services?

Patches are tested and delivered usually within 1-2 days of release by the vendors. They undergo a thorough testing phase where compliance and functionality are evaluated so that you can be sure that they are working as intended. In case you're not satisfied with a specific patch, it can be easily removed.
