In the existing codebase, if we manually assign IP to ipv6 or disable/autoconfig, either of them through NetworkStatus app, and ipv4 has no entry in “interfaces” file, then next time, the system boots up , ipv4 gets disabled.
I have made code changes (after @PulkoMandy 's suggestion)to resolve this issue. Just want to know if I can create bug for this issue on trac and then submit my patch.
Thanks.
