                But I am a very old unix/linux user and I have ALWAYS
                used dd to write
                iso images onto blank media,
                and then boot that media.
                Why is it that current linux versions of dd cannot
                write to blank media???

            Really?  I've never heard of that and I can't imagine that
            working at
            all.  If you really must use the command line to do it,
            then cdrecord
            was the tool to use, now called (or replaced by) wodim.
            But the
            "cdrecord" name still works.

    I dont know who wrote the above comment starting with "Really?", but
    the responder obviously has not tried to write an iso file to
    blank media
    using dd. I advise the responder to try it for him/her self.

        Same thoughts here. One could use /dev/cdrom, which should be
        a link to
        /dev/sr0, for reading and creating an ISO image, but not for
        setting up
        the device to burn discs "magically".

    Michael, Michael...
    I have no idea what you mean by ' burn discs "magically" '
    Who said anything about magically.

    I have been using unix since the first att release to the
    universities in the 70's,
    and linux since 1988/1989.
    Since the appearance of optical drives and media, I had always been
    able to dd an iso file directly to the optical drive in the manner
    I described.
    It was not "magical". It was "actual" :) :)

    I was hoping that an old hand at this might shed some light as to
    why it is not
    currently possible to do so.



its my suggestion he' missing the mkisofs step that wrapped the iso in a bootable/fs/partition form.

you could never boot an iso image unless it was as above...

Hi Jack.
Not sure who you are referring to as 'missing the mkisofs step ...etc'
As I indicated in my original post, the iso is the fedora 24 iso downloaded from
https://dl.fedoraproject.org/pub/fedora/linux/releases/24/Workstation/x86_64/iso/Fedora-Workstation-netinst-x86_64-24-1.2.iso

I doubt your characterization  would aply to a formal release.
