Not quite. You need to be logged in as someone who has the ability to
run the command under sudo. Yes, the first user created has this
ability. But subsequent users can do to. You can create new users under
the System --> Administration --> Users & Groups application. This
allows you to specify the type of user "Desktop" or "Administrator" for
example.

Indeed. I have a script which sets http_proxy then does an update and a
dist-upgrade, but only does "-d" with the dist-upgrade so it just
downloads but doesn't apply the updates. That way clicking the "update
notifier" icon results in very quick application of updates.

Also if you've got lots of machines you might want to put in an
apt-proxy or even a squid proxy (with dansguardian to filter out the
nasties) and have all the apt configs point to the proxy (or use
transparent proxying to force it) so that you conserve bandwidth when
updates come out.

Cheers,
Al.
