Oh, I need to conclude about this.

To think about the above case, always enabling rtadvd might
not be good idea.

And now I think the problem is that entry name,
  rtadvd_enable="NO"
is not intuitive for users.

So how about changing the name to something like,

 ipv6_to_be_defaultrouter="NO"

and if it is set to YES, then rc.network6 invoke rtadvd (and
possibly do other works)?

Please give me comments if it seems reasonable or not, and
also if the name is good or bad.

Thanks,
Yoshinobu Inoue
