I recently had a question about Drush closed as off-topic. The question dealt with Drush failing to work on a Linux server, while connecting to another Linux server over SSH.
Obviously, besides dealing with Drush, it deals with Bash, SSH, and to some extent Linux in general. However, it is still fundamentally about Drush, and Drupal developers are more likely to have an answer to a Drush-related problem than anyone on (e.g.) unix.stackexchange.com. So I'm not sure how this could be considered off-topic. It's about Drush, and getting Drush to work in a Linux environment, which is the normal environment, and the de facto standard. Since "Server administration/deployment" is listed as an acceptable topic in the FAQ, there's an understanding that some questions will touch on dealing with the underlying operating system, and other software that Drupal (and Drush) depend(s) on. That's what this question does.
So: to those who know about these things: is this off-topic? And if so, how does one ask a question that might end up having more to do with (e.g.) server administration than any part of Drupal itself? (And remember: before you have the answer, you don't normally know where the problem lies.)
(Incidentally, I don't care that much if the question is reopened. I mostly want to clarify this publicly, so either I know that such questions are unwelcome here (even though I think they should be) or the people who close questions would understand that such questions like are welcome, and should not be closed. The main value that reopening the question would have is to set a precedence that topics can bridge the gap between Drupal and closely-related technologies.)
