I would like to rename a sysctl MIB, to synchronize with KAME tree:
	old: net.inet6.ip6.bindv6only
	new: net.inet6.ip6.v6only
	this synchronizes the sysctl MIB name with the related setsockopt name
	(IPV6_V6ONLY).
	The change would break existing shell scripts (if there are scripts
	using this sysctl MIB).  will such change considered acceptable?
	or should I just forget about the rename and leave it as is?

	the old name appears in 1.5 tree too (not just netbsd-current).
