rsyncd with macports 2.5.4 on macOS 10.13.6

[Richard L. Hamilton]

You can do it yourself, in which case you need to unload the MacPorts-supplied wrapper.  But IMO, where daemondo is unnecessary, a plist without it should be supplied in MacPorts, so that it has the right name for port load / port unload to work, and so that one doesn't have to replace the plist with one of the same name (which would get clobbered on an update of the port).

For that reason, I have my alternate plist under a different name, so that I just have to keep the MacPort-supplied one disabled.

Here's what I have on an older system - I haven't tested it recently or on something newer, nor am I volunteering anything other than information, which may or may not be all wrong.

sh-3.2$ cat /Library/LaunchDaemons/local.rsyncd.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

                <key>Wait</key>
                <false/>
        </dict>

				<key>SockServiceName</key>
				<string>rsync</string>
				<key>SockType</key>
				<string>stream</string>
			</dict>
		</dict>
</dict>
</plist>


After putting the file in place, one would have to e.g.

sudo launchctl unload -w /Library/LaunchDaemons/org.macports.rsyncd.plist
sudo launchctl load -w /Library/LaunchDaemons/local.rsyncd.plist
