Besides USB being on all computers that run Fedora, and computers with optical drives shrinking; even 16x DVD is slower than molasses on a Minnesota Tuesday in the dead of winter. If time is money, and the choice is a matter of cost, then DVD is expensive.

I'm not talking about you, or me. The context from the outset was the Installation Guide, and regular users.

The Installation Guide does not mention man livecd-iso-to-disk, or any of its switches. And it would be *inappropriate*, to say the least, if the Installation Guide did refer the user to a man page.

Incantation is not in the Installation Guide.

That incantation is not in the Installation Guide.

OK thanks for scraping the bottom of the barrel.

boot.iso vs Fedora-18-x86_64-netinst.iso, presumably you prefer Fedora-18-x86_64-netinst.iso?

efiboot.img doesn't actually create bootable media, so presumably you prefer Fedora-18-x86_64-netinst.iso for that too?

And "Not available" for both UEFI install and minimal USB media, presumably you agree is incorrect, and should have Fedora-18-x86_64-DVD.iso and Fedora-18-x86_64-netinst.iso respectively.
