Deb files are deleted before synchronisation of dists/

[Daniel Dehennin]

Hello,

The inclusion of revision 70[1] resync-from-packages make the synchronisation less robust.

Before we had :

1. download new debs

2. Update indexes

3. Delete old debs

New we have :

1. Download new debs

2. Delete old debs (--delete-after)

3. Update indexes

If the deletion fails, for example if number of files to delete exceed --max-delete, the repository finish in unusable state.

Regards.
