True, but it is up to the user to modify the apt.conf (the default apt.conf
should NOT use {Pre,Post}-{Update,Download}!). So, if the user wants to manually
connect and disconnect, he shouldn't change anything. If he wants to
automatically connect and manually disconnect, he should only enter the
Pre-{Update,Download} lines.
And of course you can do a lot more than just pon/poff; you can execute any
command. Eg: I have a few workstations, and I want each one to have the same
sources.list, but I want to manually update and upgrade them (I regularly add a
source, and I want all workstations to have access to the same packages).
Therefore, I want the machines to automatically download the latest
sources.list from my server just before 'apt-get update' (or an update from
dselect) is performed, and thus I've added the next line to the apt.conf of
every machine:
APT::Get::Pre-Update "/usr/local/sbin/getsources.list ftp://debian/debian || true";
(This is actually the reason why I created the patch.)
It's really up to the user to decide what to do with the
{Pre,Post}-{Update,Download} configuration-options.
