I was speaking about the situation where there is no security update required, 
but a new version with new features is available.

No, the user has the option of not use the updates media, and the package she 
needs is in main/release.

Depends exactly how it is implemented. Either mirrors are holding all the 
packages ever released, or the package the user needs is no longer available.

See above.

So all packages ever released have to be on every mirror?

Well, either you are now either meaning:
-security update policy must be 'in event of vulnerability, upgrade, don't 
-keep every single package on every mirror

As I said previously, a security updates policy is just that, no technical 
changes need to be done vs the current Mandriva methods. However, what about 
feature upgrades (in software which have no vulnerabilities in the version 
shipped with the "big release"). Are you going to deprive users of new 
versions, because the package developers were too naive to include a 
vulnerability to ensure updates.

So, no new versions without vulnerabilities? This sounds worse for users who 
want newer packages than the current Mandriva model.

But, I wonder which of the packages in updates should have been upgraded 
instead of patched:

-apache (I vote no)
-firefox (upgraded, resulting in xulrunner and yelp requiring updates)
-samba (oden and I usually discuss pros/cons of upgrading, probably about 33% 
of the time - especially older releases - we upgrade)
-mysql (I vote no)
-openldap (I vote no, users who need newer can get from backports)
-php (I vote no)
-tomcat (I vote no)

Sorry, but to compare these cases, we really need real-world examples, so I'm 
using Mandriva 2010.1 as the basis for comparison.
