I think it is a mistake to require reboot for _every_

problems.
If you read all the posts I cited, it's pretty clear that the notion
updates are really being used if you haven't rebooted is entirely
illusory/wishful thinking. There's a good chance you wouldn't know
there were a problem.The only way to be sure is to reboot.
I don't know what the dnf equivalent is, but isn't that precisely what
the 'needs-restarting' command provided?
And speaking more broadly, a competent RH-derived-distro administrator
is already aware of this concern about libraries not taking effect. They
also have the tools (lsof, etc.) at their disposal to make their own
decisions on a live system about whether a service (or the host itself,
for things like glibc) should be bounced when updating a library package.
It feels like any auto-restart behavior (outside of the %post scriptlets
in the service packages themselves) should be advisory in nature.
