Ok, I understand. Didn't realize earlier you were also behind this
service :).

Ok, fine.

Yes, it's what I add in mind. I'll see if I can come with script, I
guess it might be useful for the main archive too.

I think given you are running the service, you are already aware of its

will never happen, however if it is the case, the kind of warranty we
would like is debian-ports being handled like the main debian archive.
