Although the phrasing may not be to everyone's agreement that particular close reason is simply a variation on your question is not on-topic. As long as the motto still is:
Server Fault is a question and answer site for professional system and network administrators.
That close reason can still stand.
The alternative is to simply phrase it both more bluntly and generic as something along the lines:
Questions must be on-topic and within the site scope as decided by the Server Fault community.
Your question may be more appropriate and on-topic in one of the other related Stack Exchange communities.
Possibly including a link to a recent discussion on Meta about the site scope.
