Hi,
you don't *have* to reboot the server. If you don't there are two
factors you need to consider:

1. The updated component are not all active without a reboot

The kernel for example will obviously not not be running without a
reboot and the same may be true for other components. For most
applications you should be ok if you just restart the application so it
can load in the new libraries.

2. If you reboot later issues after the reboot might become more
difficult to debug

If you reboot e.g. 6 Months after you made an update and the system
doesn't boot properly you will most likely have forgotten that you
updated the system a long time ago and look for more recent reasons why
the system doesn't boot. If you reboot the system immediately and it
doesn't come back up you'll know that most likely the update has
something to do with it.

So if you don't reboot the system should still keep working normally but
for the above reasons you might want to reboot it anyway of not right
away then at least in the not too distant future.

Regards,
  Dennis
