The page https://getfedora.org/workstation/prerelease/
mentions using the
fedora media writer to write ISOs to USB drives.
It says you can download it using dnf, but it does not give the package name.
The package name is "mediawriter". It would be nice it it actually said
that next to where it mentions it. (The link goes to something that does
not mention media writer.)
