I understand you are talking about /proc/sys/net/ipv6/conf/default/*
controls. If so, it's ok, but I talked about /proc/sys/net/ipv6/conf/all/*
controls. Documentation/networking/ip-sysctl.txt says:

    conf/default/*:
	    Change the interface-specific default settings.


    conf/all/*:
	    Change all the interface-specific settings.

so what is the difference between default and all in the context of your
statement? In my opinion, it could be understood that default settings
are inherited and those from "all" directory change values for all
current devices.
