Subject: Please provide a stable link to the DVDImages

Date: Fri, 5 Feb 2016 12:15:39 +0100

Package: cdimage.debian.org
Severity: wishlist

Hi,
tools like libosinfo keep a list of URLs to installation media. For
Debian the URL needs to be udated for every point release since there's
currently no stable URL. See e.g.:

    https://git.fedorahosted.org/cgit/libosinfo.git/commit/?id=202acfef63226f72dcca843307ca773f72a46f6a

and the images of old point releases are removed from the server. While
there is a current link for the folder there is none for the DVD image
atm:

    http://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-8.3.0-amd64-DVD-1.iso

Would it be possible to get a stable link for the DVD image as well
like:

    http://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-8-amd64-DVD-1.iso

which would then point to the latest point release?

Cheers,
 -- Guido

(I'm cc'ing the relevant Debian bug report.)

While using the archived versions is great for older releases I guess we
should stick to the current URL.

Another alternative would be a reflection service. I've set up

    http://cdr.debian.net/debian-cd/8/amd64/iso-dvd

that would redirect to the current stable URLs. That would put the load
of switching URLs on my end alone but having a non-official URLs in
osinfo-db looks bad but it does allow for stable links to the current RC
candidates that won't change on release:

    http://cdr.debian.net/debian-cd/9/i386/iso-dvd

so we could add Debian stretch just now.
