Nope. Just the binary *.deb files and only for 386.

Mirroring both binary-all and binary-i386 isn't really a problem, it's
just unecessary for a one-version, one-architecture mirror. Before
potato that's how I mirrored slink. But slink didn't have any
connections to other distributions. When I first started mirroring
potato it was heavily connected to slink with symlinks from
potato/*/binary-i386/ -> potato/*/binary-all and then a mess of links
from there to slink/*/binary-i386 and slink/*/binary-all. It would've
been a mess to try and get a one-architecture/one-distribution mirror
out of it. I imagine the situation between potato and woody is
analagous now, with lots of stuff in woody linked to potato. 

Around that same time something happened to all the major mirror sites
as well and they quit allowing "ls -lLRat" to flatten symlinks. So, if
you wanted a mirror via ftp then you were almost forced to get potato
and slink with both binary-i386 & binary-all.

As to what happens if I want to add another distribution, I
won't. This is a private mirror for myself and the few folks here also
running Debian. It's behind a firewall and not accessible to the
general public. When I feel woody is stable enough for daily use I'll
quit mirroring potato and switch to woody. Anyone here wishing to stay
with potato will just have to change their apt sources.list file to
point to a standard mirror.

Well, I've had good luck as far as keeping the mirror up to date. Our
proxy servers reliability is another matter. Always seems to die about
3/4 of the way through, when I'm doing a large mirror. End up having
to do part of the mirror manually, but it works and it makes it easy
for me to take a copy home and upgrade my home systems, as opposed to
trying it over a 49k modem line.
