For that to be involved, you might be creating the socket from a script instead of as part of your package payload. Either have your application create the socket at runtime and assign correct permissions then, or make the socket part of your package payload. Agreed. Although as the launchd maintainer, I'd rather see the socket created as a part of the launchd job schema outlined in the property list, but that is my personal agenda. :-P The socket is not created by the installer.
