Ah, so you're saying that ipv6 is missing from micro's DISTRO_FEATURES?
If that's the case then it's just a bug: presumably it's been harmless
in the past because very few packages care about it.  Irrespective of
that, the intended behaviour is that micro should be IPv6-enabled and
turning it off in busybox does not seem like a good idea.

Actually, a quick "grep -ri ipv6" in conf/distro didn't turn up any
matches at all, so enabling IPv6 by DISTRO_FEATURES doesn't seem to be
terribly well entrenched at the moment.  If it were to be introduced
then I suspect it would need to be a negative property (i.e. the feature
would be "no ipv6") in order to not break all the existing distros.
