Disabling automatic upgrades on Sid by default?

["M. Zhou" <lumin@debian.org>]

Hi folks,

I don't quite understand the meaning of automatic upgrades on a rolling
system such as Debian/Sid. According to my own experience, such
automatic upgrades could be dangerous.

Recently package ppp is pending for upgrade but it does not co-exist
with my currently installed network-manager. Today when I was shutting
down my machine, Gnome automatically checked the "install updates ..."
box for me before I realized its existence. As a result, the system
reboots and installed ppp by force, removing network-manager and break
my system for daily use as I need network-manager for wifi-access.

I've been a daily Sid user for at least 4 years. Automatic upgrades are
to blame for nearly all my system troubles. And I feel very
disappointed every time linux behaves like M$ windows.

So, do we have a consensus on whether automatic upgrades should be
enabled by default?
