But how is it possible to distinguish a priori between a backport which
will be an update and one which will be a "new" backport on a users'
system. It would only be an "update" if the user has already installed
the corresponding backport on their system.
If the fact it is a backport is ignored, then every backport would be,
by definition, an update. Even packages newly imported to Mageia.
To me, a "corresponding" package is one from the same category,
according to whether is is backport or not, and according to whether in
"core", "nonfree", or "tainted".
To consider otherwise is to deny the importance of these categories.
Backports are considered separately because they are much more at risk
to not function properly, since they weren't tested with the rest of the
release, being added afterwards. So we have to be much more careful
about adding them. The last thing we want is for the backports to be
included automatically with updates, even if the user had not already
decided to install the corresponding backport. Installing a backport
should be an exceptional, explicitly decided activity -- except when the
user has already decided to install the corresponding backport, when it
is useful to present newer versions as updates. They are likely
security or bug fixes.
