@kasperd the fact that Ubuntu doesn't do some things wrong is no proof that it does all, or even all important, things right. Also, CentOS does exactly what you describe, unless I've misunderstood you (except that you get seven years life, not five).

@kasperd I hear you, and you make a good point, but to my mind it's yet another reason why Ubuntu isn't really suitable for server deployment. I know this point of view may not be popular, but I'm definitely not willing to cede to Ubuntu the right to determine what constitutes "best professional practice".

No. If you're seeking help from peers in this case, you're a professional sysadmin who understands IP networking and the nature of first-dispositive-match-wins filters; unintentional ignorance at that level is sloppiness. Or you're not, in which case you're not asking peers, you're asking seasoned pros to give up their time to help you.

Oddly, I know about the community bump - and it only affects two posts an hour, which I can live with. If you think edit farming doesn't happen, I recommend doing the edit review queue assiduously for a few months.

Edit farming is the practice of low-rep users systematically making minor fixups in a large number of posts in order to reap the edit bonuses. My feeling (and it's just my feeling - this is meta, after all) is that old questions with no answers are probably bad questions (or they'd have answers by now) whose askers have long since gone (any sysadmin problem you haven't solved after five years is irrelevant). I have no desire whatsoever to see them re-appear on the front page, least of all because they've just had errors corrected that should never have been there in the first place.
