What you're trying to imply here is that linux effectively needs to be reboot on every update, and you're wrong. It's possible your cloud provider has chosen to have its own package repository where they insist on doing this, but this is a decision by your cloud provider and not Canonical. Linux has what's called Kernel Modules that can be unloaded and loaded at runtime without the need to update the kernel itself. I myself run ubuntu in vmware, and have done so for probably over 10 years, and your description of Ubuntu's default behavior is inaccurate. --- But more than that, it's been explained to you, stop arguing.
