In general you have to stop and restart whatever is installed new. If a
new mysql server is installed, mysql will be stopped and restarted, if a
new x-server is installed you will have to stop and restart your x-
server. If a new kernel is installed, the only way to get the new kernel
running is by stopping the old one and restarting the new one and that
means a reboot. Apart from the kernel almost everything else can be
stopped and restarted without a reboot. There maybe some exceptions, but
I don't know them.
