Yes, I think we agreed with that and the wording we are using for the current (and future) FreeBSD situation just differed. To rephrase: I think it is a good idea (especially given the startup script use it) to have a command to send ICMP echo requests for a supported protocol family. I also think it would be a good idea to preserve the legacy of ping6(8) which behaves exactly the same as the current ping6(8) even if the code is shared with ping(8) and installed as a hardlink or similar. /bz
