I wanted to support a commentator who pointed out that the question was off-topic for the Unix site and should be better put on either SuperUser or ServerFault. However, when performing the steps to flag the question, the only two migration options were "stackexchange" and "meta.unix".
Maybe offer a wider choice of migration options? It could be a selection box from all StackExchange sites, which would cover all possible options.
EDIT: Questions More options when flagging for migration and Add "Flag as Other" checkbox to "Vote to Close as Off-Topic" dialog don't present a clear resolution and final guidance, and the voted proposals have clearly not been adopted.
