indeed, this may qualify as the project's first finding. my comments below:

this is what we should do. bind9 is simply wrong in this case, since
it's necessary glue.

mark andrews will likely agree, and the patch would be on a faster cycle
for that reason.

this should not be done, because it won't scale, and would lead us to

...that the IANA approach is somehow correct, which it is not. we should
not constrain our design to what works with current software, since our
goal is to determine how the system, and its software, should work in
we have a fifth alternative here, which is to put all of the root server
names inside the root zone itself. i am very interested in this
approach, since rssac-caucus is now starting work on analyzing this
approach, and we could help inform that discussion by our work here.
briefly, we would have to create a top level name (which is a policy
violation, so, would require study) called "yeti-root" or similar. this
would not be a delegation point. we would assign names under this
top-level, such as tisf.yeti-root, wide.yeti-root, bii.yeti-root, and so
on. these would be added by the distribution masters after stripping the
IANA apex NS RRset and while adding our own apex NS RRset. thus the glue
would move to be in-zone, and it would be signed with the yeti DNSSEC key.
i think we should explore #5 and #2 in parallel, and that we should be
certain to use both during the three-year expected duration of the
