(I forget +the other details.) + +They need a single line of code, something like + +rsync -ra {URL-source-directory} {local-destination-directory} + +This is very easy to do : Mageia gives the source URL (and the options +required), and the mirror site knows the destination directory. + +This line of code is put in a cron (or acron) job file, configured to +run automatically at the specified regular intervals. + +If they exclude the optional "tainted" repositories, they have to add an +"--exclude" option with the relative path to these repositories. +(Still in a single line.) +Fairly straight-forward. + +Why system admins in multi-mirror sites with lots of other tasks would +like to avoid optional repositories is that they are probably already +overloaded with things to do, and adding the exclusion multiplies the +risk of having a (tiny) error that makes it not work. +Also, a minor change at the Mageia source could make it stop working. +The last thing they need is another problem. + +><i> [...] +</I>>><i> +</I>>><i> Note that if, down the road, we find another effective method for +</I>>><i> distinquishing core / non-core, it is relatively simple to transfer +</I>>><i> packages in "extra" to "core". +</I>>><i> But if we eliminate the parallel set of repositories, and find later +</I>>><i> that we have a problem giving priority to core packages, moving in the +</I>>><i> other direction would be a much more difficult process. +</I>><i> +</I>><i> IIRC someone with experience said in this thread that we could always go to +</I>><i> that sort of scenario if like this it wouldn't work well.
