I am a bit suprised that such a "serious" guy can wrote this on slackware. By experience, it's the most secured linux I know. People before me add comment on the mailing list, and the repository of patch. You can notice there are few patches, it's because Patrick Volkerding has always take care of security in his distribution of linux before releasing it. there are also less packages than other ones but I sleep better.
Your article is interesting, but I have the impression you only tell obviousness : Yes, of course, users concern by security have to look for tools (mailing list web page, etc ...) that give distributions before making a choice. It's obvious !
But let's consider an another fact, security is not a goal for everybody, even if I think it's a bit dangerous. You simply want to be dictator, choosing for everybody the good way...
An another point to answer to jwz, if you can't spend half an a hour per day for security issues, security is definitely not a concern for you, sorry. I'm a bit curious, what is your model of security OS ? Windows ? So you never had a look on securityfocus (and others).
I can't see how we can have security actually without spend time for it.
The power of linux is in distributions, everyone can find his "good" distribution, so let the people of distributions works, help them, ask them for new features, but don't ban them. You are missing the real enemy and misunderstanding the open software.
