that doe snot mean ipv6 has to be mandatory

completly different topic

the installer is not connected to the network and ipv6 was laways enabled
by default, *but* until now i found no way to diable it on F19 with a F20 kernel

no - that is not a feature
see the bugreport above

there has only be a clear way to disable it which does not change
randomly - maybe you think i support the proposal disable it by
default which is *not* the case, i only *need* to disable it for
security reasons in *production* environments and as admin it has
to be *always* my job to deice if a device needs whatever
network protocol supported

i did not propose this with *any* word!
