Huh ? Isn't it the autoconfigured address you expect to get from an "auto" stanza ? >> Does that suggest a bug in ifupdown? Or am I interpreting something wrong?

Yes. "auto" sets autoconf=1 to enable SLAAC, and "static" sets autoconf=0 by default, which disables SLAAC and removes any autoconfigured address. > I can also make it work by adding 'autoconf 1' to the static stanza, and > omitting the auto stanza. This is the right way to go.
