QEMU options are single dash with double dash accepted for compatibility but help and other docs have single dash so these (and below) should be -trace. (Also a bit less typing for otherwise already way too long command lines.)Is this documented somewhere? I was under the impression that '-' is legacy syntax and '--' is the preferred syntax. There are examples of '--' on the QEMU man page. Let's reach agreement, document it, and then make the documentation consistent. Stefan
My naive impression was that double-dash is the preferred idiom in linuxdom in general for any multi-character option.
We might hang on to single-dash for backwards compatibility, but I doubt we want to enshrine that as our preferred way.
Is there a reasoning I am unaware of?
