Should package integration be disabled by default? I know a lot of Linux
people who are a little unsettled by how much Ubuntu attempts to automate
things, without users' control or knowledge. Not all those arguments hold
water, but if a firewall were opening and closing ports on a system without
the admin's express, explicit consent, it could quickly drive away the
users this could benefit.
As the disclaimer goes with EVERY post I make to the MLs here: I am not an
expert, and I am not an active developer here. I am asking that it be
considered, if it hasn't already, that package integration be an optional,
if not disabled-by-default, feature. Let the admin know (with confirmation)
that package integration is on, and that the OS will attempt to
"inetlligently" (emphasis on quotes) adjust firewall settings based on
It could be argued that if someone wants full control over their firewall
they could just use iptables, but meh.
