The ISOs we have to consider are:
* Live images [[BR]]
* DVD images [[BR]]
* boot.iso / netinst.iso images [[BR]]
* install.img image [[BR]]
The writing methods we have to consider are:
* dd (and equivalent utils, e.g. Windows tools which just do a simple raw
image like dd does) [[BR]]
* livecd-iso-to-disk [[BR]]
* liveusb-creator [[BR]]
* unetbootin [[BR]]
There is possibly more to it as well - for example in the past I have
tried the dd method and it sometimes works and sometimes does not -
but I never got to the bottom of that.
There are possibly issues with whether or not the usbkey is labelled
and sometimes what the partition structure is.
Also in the past I have had to resort to booting the boot.iso image on
the key and then referencing the DVD iso file via an HD install (with
its associated images/ directory) placed on the same key in the root
directory - which did work, where booting the dvd iso directly on the
key did not. Should booting an install dvd iso directly on the key
*always" work?
In addition sometimes which usbkey is used can make a difference -
Also there is the (possibly not Fedora problem) issue of getting a
usbkey to boot on old machines where usb boot is not available from
the BIOS.
All these issues tend to make the use of usbkeys less than 100%
reliable - anyway I will run some tests with the beta trying to
install from usbkey - and report back in due course.
