Technically speaking, an ISO image is a "disk image" (which means a
single file containing the "image" of a complete file system) that
contains an "ISO 9660 file system" (which is the file system format used
on CDs and sometimes DVDs).

Wikipedia: https://en.wikipedia.org/wiki/Iso_image

I admit that we've used this terminology since the project started
without really thinking about it and because it's the usual way of
referring to such files in the Linux world.

I looked only at how other projects refer to these files. All of them
still use the word "image" but almost none clarifies the format (which
might be different than ISO):

Seeing that, I'm not against getting rid of the "ISO" word but this
would require adapting this terminology in many other different places.
Starting with our installation instructions. It might not be undoable
but would require thinking more about whether getting rid of the "ISO"
word would work in all the different places and doing the work of
changing them.

Right, what Thomas said made it clear that we need to clarify that the
installation will only work with an Tails ISO image (and not an Ubuntu
ISO image for example). So I think that we need to specify that we're
talking about a "Tails ISO image" here.

The goal here is to make it clear that the user can, in your USB stick
situtation, *either* clone (install a new USB stick by copying the
current Tails that she is running from) or install from an ISO image
that she had downloaded.

Cloning would always work but installing from an ISO image requires a
previous download. I thought that using radio buttons would made the
alternative explicit (you don't need to download an ISO image to clone).

Definitely.

Ack. I added both things in the screenshot in attachment.

This one can be displayed in place with some more explanation about ISO
image and the difference with cloning. It would also have a link to the
installation instructions.

NB: I'm putting back kurono in copy. He was dropped but I think that
he's not on tails-ux.
