Debian packages moved from alph.gnu.org into mirror system?

[Patrick Strasser]

Hello,

I'm working on jigdo templates for the J-series of the Debian/Hurd CD 
images.

It looks like the dists/sid/local/binary-hurd-i386/ directory contains 
the files that were on alpha.gnu.org/gnu/hurd/debian/ when the image was 
produced. Now some of these packages seem to be on the Debian mirrors.

This is crucial for generating the templates. The template needs to know 
where to get the files from. If the files are moved they cannot be 
included in the image being reconstructed and renders the image almost 
certainly useless.
If I know a position the moved file can be expected to appear again, 
things are not that bad anymore.

Is there an automatic mechanism when files are moved from alph.gnu.org 
to the mirrors? Is there a fixed place to find the files again?

Additionally, can someone please explain the typical life cycle of an 
Debian/Hurd package?

Regards,

Patrick
