On Red Hat 7+ and derived distributions, 'nc' is nmap-ncat, but on Debian based distributions this is often netcat-openbsd. Both are mostly compatible with the important distinction that netcat-openbsd does not shutdown the socket on stdin EOF without also passing '-N' as an argument which is not supported on nmap-ncat. This has the unfortunate consequence of hanging qmp calls so tests like aarch64 its-migration never complete. We're depending on ncat behaviour and nmap-ncat is available in all major distributions.
