Well, then we partition it off by year or whatever size unit it works
at? It is also possible improvements in the underlying filesystem and
disk technologies over the years make it more viable now than in the
past?

I definitely don't have more than a few months using this method at this
time, so sure, it could all come screetching to a halt at some
point...

I can continue to backfill from snapshot.debian.org until it breaks, I
suppose. :)
