One problem not rebooting with the kernel is drivers. They aren’t all built in. Most distros leave the current running kernel and boot into the new one next time. Some, like Arch, overwrite the kernel on an update, so modules can’t be loaded. It is a shock the first time you plug in a USB drive and nothing happens.
