How does this work in terms of Linux distributions picking up your fork? Does something have to be submitted to each of them to show that the original maintainer has left the project and how would they decide to use your fork? I've always been curious what the decision making and vetting process around that looks like. I know in this case it's a shell script anyone can download and drop into their ${PATH}, but that isn't always the case.
