OK, so the main issue is that the implementation of ipv6_enabled() is
inadequate for detecting that ipv6 is disabled on this platform.

+1

I have no idea how to fix this.

It looks like sysctl uses values from /proc/sys/net/ipv6/conf/*/disable_ipv6

  • that might form the basis for a more robust implementation. Looks like it can be disabled globally ("default") and/or per-interface.

[...] does not prevent the use of the -i option to add
other interfaces. The man page suggests that -i should perhaps be
disabled in this mode.

Yeah, and/or we could make use of the per-interface enabled/disabled
state from those procfs files.

cheers.
