From the other threads on this topic, this was not entirely true. And
now, there are many more moving parts so the chance of running into a
problem are higher. If you update libraries, you have restart all the
services that use them. And your point about logging out of X defeats
most of the purpose of doing a live update anyway. Most people want to
do it to avoid closing their open applications. And updating something
like LibreOffice or Firefox while it's running is just asking for trouble.
