Looking at the code, I see that the default for all namespaces will be taken from the ipv6 module parameter "disable_ipv6". This parameter is not writable and the ipv6 module is built-in, so you cannot change it after boot. But booting with "ipv6.disable_ipv6=1" on the command line should work. Bjørn
