This may seem to be a stupid question, but .
I can download a iso image of Fedora, then do a sha256sum of the file
and I get the result shown in the SHASUM file.
I can burn a DVD with k3b, ask for it to verify the checksum, and
have it say the checksum is OK.
But if I just do
sha256sum /dev/cdrom
I get a result which is NOT the published sum, even tho k3b said the
sum was going to be OK.
So what am I doing wrong? (and yes cdrom and dvd both point to sr0)
