This ugly thing is a shell script to detect availability of the -q option for 'nc': debian and suse based distros need this flag to ensure the remote nc will exit on EOF, so it will go away when we close the tunnel. If it doesn't go away, a useless 'nc' process is left sitting on the remote host.
I've spent time trying to make this code more flexible with other types of relays, e.g. socat which can be invoked with socat - GOPEN:sockname LIBVIRTD_PRIV_UNIX_SOCKET but haven't come up with anything I would consider upstreamable. Jonas Eriksson also made a brave attempt [1] :-). Any suggestions for improving this code to handle other relays at runtime?
