Cleanest way to find out if it was a --dry-run

[Dave Gradwell]

I am trying to determine this from the daemon-side, where the daemon is the receiver to a remote sender.

Indeed, it's quite clear at the client-side.

It was exactly this sort of thing I was worried about...
Can you elucidate on the 'nonofficial passing' bit?

Could you be sure this wouldn't create any false positives?  If the '--dry-run' argument was represented more literally at the daemon side then I would be less worried...

Is there no other way to determine that it was a dry-run more explicitly?

With thanks, Dave.
