my bad, will open a pr shortly

in the mean time, this is the code for it:

#[cfg(target_os = "linux")]
fn main() {
    use std::os::fd::AsRawFd;
    use ztunnel::test_helpers::inpod::start_ztunnel_server;

    let uds = std::env::var("INPOD_UDS").unwrap();
    let netns = std::env::args().nth(1).unwrap();
    let mut netns_base_dir = std::path::PathBuf::from("/var/run/netns");
    netns_base_dir.push(netns);
    let netns_file = std::fs::File::open(netns_base_dir).unwrap();

    let fd = netns_file.as_raw_fd();

    let (default_node_server, mut default_node_server_ack) = start_ztunnel_server(uds);

    default_node_server.blocking_send(fd).unwrap();
    default_node_server_ack.blocking_recv().unwrap();
}

#[cfg(not(target_os = "linux"))]
fn main() {}

i'll need to validate this still works against main
