Some binaries use $0 sniffing to determine what mode to use. So, we
want to propagate the argv0 we are using so we can use these programs.
A good example is “coreutils” which uses this method:

Thanks for making this change. I'm not sure we can use this method -- It sounds like you're not calling including the binary in the tarball and calling it with a script, but rather inlining the binary, using |

Oops didn't consider that! It's definitely good to avoid that.
The binary is still in the tarball. The problem is I don't want to hardcode the binary name into it. So for instance, I would like to be able to make a symlink on the outer arx script so that it propagates to the inner "$0". Here is a good way to show what happens without using I'd like it to show |

It needs argv0 to be set to the real name of the utility. Before it was something like
