Well maybe I'm not understanding your proposal.  Initially I thought it 
was to remove the update option at the end of the upgrade process with 
the DVD.

Then a post earlier in this thread said that you didn't mean that, and 
seemed to say that you were suggesting removing the upgrade install 
option with the DVD, leaving only the clean install.
If so, I am strongly opposed, as in my experience, for the reasons 
cited, it has been by far the best upgrade path for myself, and I'm sure 
for many others.

However, maybe I'm misunderstanding your proposal ?

Maybe the introduction of systemd introduced a one-time transition 
problem which will not normally be encountered with a DVD upgrade install ?

Sorry, just trying to put my approach in context.

That is not the same thing as saying that we should *prevent* using the 
DVD for upgrades.
In any case, with the reliability of Internet connexions available at my 
location, it is highly unlikely that I could make an upgrade without the 
DVD.  And during a DVD upgrade, I don't have Internet access.  (My 
Internet supplier usually cuts the connexion if not active for 5 
minutes, which always happens with a DVD upgrade.)

Sorry, but I think that even the least computer-savy user could easily 
use this approach.
1) Do upgrade with DVD
2) Reboot
3) Do update with MCC/software/package_installer (rpmdrake) or 
update_system (mgaapplet)

Since an upgrade install only removes packages that are replaced, 
nonfree firmware stays installed. Also packages not on the DVD stay 
installed, even though not updated until step 3.

Note that on Microsoft systems, it is generally recommended to reboot 
after installing, even for relatively minor upgrades.  Instead of only 
after a release upgrade.

If the user has reliable Internet access during upgrade, of course it 
would be advantageous to do it in one step.

Note also that at least in North America, users can usually download a 
DVD for free at their local library, even if they don't have a good 
Internet connexion at home.  And in other regions, users could obtain a 
copy of the DVD without having to download it themselves.
So the DVD upgrade install has its' place.

Regards :)
