[tex-live] burn inst image?

[Karl Berry]

    my experience is that a 700 mbye CD comes in at
    about 720mb file size. 

Mkisofs is reporting extents of 692mb.  Isn't that the relevant thing?
I see the file size is only 694mb, though, and my experience, like
yours, is that there's usually a bigger differential.

    so I'd say you have lots of space free (relatively)

Relatively.
