Both scripts run for real with PATH holding one directory that carries a tcpdump stand-in, which records the path and arguments it was started with. The plain run stops at the interface step, before any socket or capture. The capture runs inside a private network and mount namespace, where the loopback interface is the only one, its default route keeps the DHCP discover on the host, a tmpfs over /tmp holds the dump file, and /usr/sbin/tcpdump is hidden so the previous guard fails there on every host. Hosts that cannot create the namespace skip that part.
