Do I understand 'you' correctly? I use 'you' for the "very useful for
people". Okay?

*If* 'you' downloaded the *whole* 3.4G Fedora 11 DVD so that 'you' could
upgrade an installed Fedora 10 machine and the upgrade installed *some*
of the packages from the DVD and downloaded and installed *some* of the
packages from The Internet that would not make sense to me?

Some of the packages on the DVD that 'you' just downloaded where updated
the same day Fedora 11 was released. So those files, that 'you' just
downloaded in the ISO, were already old and not used. The newest ones,
and their dependencies, were downloaded anyway. Many of the packages on
the DVD which 'you' just downloaded where probably not used at all
anyway. But you just downloaded them in the ISO.

If you had several, many, machines to upgrade that could make some
sense. But not for one machine. Or two very different setups.

I actually did an upgrade of a Fedora 10 Desktop system to Fedora 11 as
a test. A Fedora 10 install up-to-date the day that I did it. My
download total was less that 900M. No where near the 3.4G DVD or the
extra packages they 'you' would have downloaded.

So please explain to me how that would have saved "very useful for
people" any time and any bandwidth?
