Well, just an rsync over the entire debian-cd directory doesn't work that
way for me, unfortunately. Because it handles the 2.x dir first, before it
comes to the potato_test dir.
And if you only rsync the potato_test dir (and make links manually or
scripted later) you need addtional storage, because then you will end up
with the new set in potato_test and the old set in 2.x. This might work
fine for some people, but unfortunately we do not have that much storage
free (we use that to mirror stuff instead).
I wonder if rsync could be convinced to operate with checksums and so for
an entire fileset.. That would mean considerably more work for the server
though, so the caching checksums feature is probably something that must
be implemented first.
