      Note that we are taking a completely different approach to tunelinux. We're breaking it down into functional areas rather than specific applications. For example, to tune a, oh.. let's say samba server, you need to tune SAMBA, the kernel and a number of other things to get the best from your box. If you take the tunelinux approach, you'll only end up with a 50% solution because you'll just tune SAMBA, and not the kernel. The Mindcraft report is a classic for that. Yes, tune samba, but hey, the kernel still only uses 960MB of RAM. The "tuning samba" doc approach wouldn't cover that sort of information all in the one spot. Effectively you end up with the same problem as we have now - lots of documentation but so fragmented that you can't do anything useful with it.

    Well, yes, that is the first and foremost danger, probably. I've experienced this myself, once accidentally deleting my main .netscape folder when I thought I was in a different directory (or something, it was late at night.)

    Besides this, if you are using root for your day-to-day work, you might run a binary or script that would be a big no-no to run as root. Like some malicious trojan horse code. While there is always a slight danger installing any software that you haven't thoroughly reviewed, this danger is lessened when the software is only run with the priveleges of a normal user.

    If you are running a strictly single-user system and are not connected to a network, you could probably "get away with" logging in as root all the time. But there is no real reason to do this, just create a damn user! Unix security will protect you from your own late-night ineptitude!

    I'm not worried about the security implications of telling people about the root account. I'm well aware of the fact that virtually every Unix box has one. What worries me most is the impression it gives to the world to tell people to email you at root instead of a regular account. In my experience, everybody who knows anything at all about system administration tries to minimize their use of the root account. Conversely, the people who use "root" as their primary account instead of creating a non-privledged account are almost by definition inexperienced and/or lazy.

    I think it's a great idea for the Linux community to have a resource for tuning information. However, if you want that resource to be taken seriously the people running it at least need to look like they know what they are doing.

Someone who has managed to get root's mail aliased to some other account also knows that it takes abount 10 seconds to create an arbitrary alias to use for situations like this.
