A quick grep over all unpacked packages shipping ifupdown hooks show 60
hook scripts which don't have ADDRFAM set.
I haven't checked them individually, though.

What I'm not happy about is, that such a change was made without
notifiying the affected package maintainers *in advance* with clear
instructions how to address this. Ideally via the BTS.
Such documentation and instructions are still missing.

Andrew, care to explain what a package maintainer is supposed to
consider when shipping such a hook? The existing documentation is rather
scarce on this topic.
