Hi Ole,

glibc does at least, but for it to work the the interface ID must be
written to /etc/resolv.conf. That's a corner case that isn't
necessarily immediately obvious to the developers of the piece of
software that interprets RAs.

I can't help but think that if RFC6106 had explicitly mentioned this
corner case, bugs such as
https://bugzilla.redhat.com/show_bug.cgi?id=720001 could have been
prevented. So I'm with Lorenzo on this one.
