However, since you didn't explained at all what are the issues you are
facing with the new approach, and since you have only explained how you
are doing on your 20 servers ( which is totally unrelated to the
question of desktops, BTW, and which would still be usable at your
convenience on anything you maintain ), I am quite sceptic on your whole
intervention.
The issues are that:
* updates require 2 reboots,
* you cannot use what you upgraded before doing the reboots,
* in particular, you cannot install new packages built against the updated
ones before the reboots,
* security fixes also only take effect after the reboots.
