I wouldn't do it (writing an iso over the network from NFS storage, due to the network possibly messing up the integrity of the iso image) but you should still be able to with the "dd" command. Issue a "mount" command and you should see the mount path of your NFS storage. Then, as Bob explained, do "dd if=/path/to/NFS-storage/image.iso of=/dev/sdX bs=8M status=progress oflag=direct"

this all good information but I have never used media writer to create
the fedora.iso installation media. n a released version there is
normally a webpage offering a download which I save and can put on a
thumb drive, cdrom, whatever.
Media writer has a "custom" which will see read the .iso from the copy I
saved in "Downloads." In this case I have the Fedora 33 beta .iso and
tried to use that file from my copy on NFS. the problem I had was it
could not be pointed to the install location, it insists on using the
4TB drive on my LAN, and it appears that would work but it's not what I
want and normally do. I have another drive in this computer with Fedora
31 on it and that drive should show as an available install target in
the media writer gui.
That is how I have done. Sometimes I create install media on a flash
drive, but I have had some instances where the flash drive is not
recognized?
However this is just something I thought I would do but does not work
and I can wait until the released version is available, in which case I
would have liked to know how to avoid the media writer application that
I always find difficult to use, but always muddle through.
Thanks for the help, Bob
