Other than reboots forced by power outages or changing hardware, IIRC
you need to reboot 1) when you install a new kernel, 2) when you install
a new version of glibc, and 3) if you turn SElinux off or on.
Practically everything else can be managed without rebooting, though for
many people (especially desktop users) it's easier just to do it rather
than work out if it's required.

Note that updating Gnome or KDE does *not* require a reboot. Just log
out and in again. The same goes for X itself.
