But it's not as if I hadn't done some searching on my own before I posted the question. I tried several pan-forum searches using different terms. I'm generally pretty good with Google, but clearly, I didn't ask the right question, or I asked it the wrong way, or didn't use terms the search engine understood, but I found nothing relevant in the results. So, I asked! So, SHOOT ME!
What's more, I made it clear that I had been away from the Linux/Ubuntu community for a while, so it was to be expected that I was not up to date.
Considering all this, I thought the rudeness was unwarranted and unjustifiable. Sometimes, I think people are "testy" because it makes them feel superior - not to mention safe - to insult people through the faceless anonymity of the online world. Personally, I think it is cowardly. It's easy to insult someone you can't see, whom you can easily imagine as a 5'4" 120-pound pencil-necked twerp (like Howard Wolowitz on "The Big Bang Theory"). It's harder to insult someone if you are face-to-face with him, especially if you can see that he is in fact a bearded 6'3" 300-pound walking brick with arms like a gorilla (like #61 Joe Hawley, offensive lineman for the Atlanta Falcons).
I suggest that if this is a question that has been addressed "over and over again," the subject would have been an excellent candidate for being included as a sticky post, or as part of an FAQ or "Readme" for newbies. Further, I suggest the deployment of a more intelligent search engine that is better able to infer from a wider range of possible queries and provide results that are more relevant.
