Reboots are needed if you got a new kernel, or new firmware, or new
microcode, or a new version of the dbus package (because dbus cannot
be restarted).
And if there was an upgrade to a major C/C++ library, you may find a message that
running processes using those libraries will be running on the older library versions.
Only newly started processes invoke the new versions. So if a library bug is causing you
a current problem, init itself or kernel-space code may need to be reloaded. So a reboot.
