ansible fetch fails but creates zero-length file

I made a mistake – it’s not “for whatever reason the file cannot be copied” ... but it happens (at least) when I can’t open the remote file (permission denied).

My problem isn’t “the file didn’t copy”. I know why the file didn’t copy.
The question is, why did a zero-length destination file appear when the file didn’t copy? If the file didn’t copy, then my destination should not exist.

I think not using become is what is killing you. iptables is definitely only readable by root. Try turning "become" back on.
