	Yes for an upgrade to a newer release but not for an update to the
latest patch level, there old kernel should support the userland just fine
(modulo bugs) and so a reboot is only needed if there is a new kernel.

	That is indeed the simplest and safest way to ensure that everything
that needs to be restarted is, but not the only way.
