The general answer is that it doesn't matter: whether you installed with the DVD or a live CD, you will get a Fedora system from which you will be able to install and remove packages in the same fashion.

There are a couple of differences worth mentioning, though.

Default packages

The live CDs are called "spins". Each one represents the focus of its authors. For example, we have a Desktop spin which will result in a GNOME desktop with a certain selection of applications. The Electronic Labs spin will in turn bring in applications tailored to a very different purpose, etc.

Using the DVD, you won't get the same kind of "good defaults", but you will be able to chose right from the installer which packages you wish to install.

Think of it as a question of convenience vs flexibility.

Again, nothing prevents you from installing the Desktop spin and then manually installing some applications part of the Electronic Labs one. It's all about defaults.

Customization

Apart from installing different packages, some spins could chose to customize the system further. For example, a spin targeted at average users could decide to allow the first created user some administration privileges, like updating without needing to enter a password. On the other end, a spin targeted at hardcore sysadmins would be completely locked down in its default policies.

Again, these are only defaults which could always be overriden after installing.

To my knowledge, although there have been lots of talks avout these kinds of customization, there aren't any such yet.

Performance

Installing with the live CD is much faster.

This is because the live installer will simply copy the live system on the target hard drive and then resize the partition.

On the other end, the DVD installer will use yum to install all the packages, which is noticeably slower.

However, the partition resizing trick leads to a minor, theoretical loss of performance of the file system of the installed system. I believe this has not been measured to be significant though, and the plans for the future of the live installer seem to be to use yum as for the DVD one.


As you can see, both method will give you essentially the same result, and as for everything else, it's merely up to which one suits you best.

Of course, there are other points to consider, like the time to download, the necessary capacity of the installation media, etc.

Hope that helps!
