Because ISO filesystems are created before being written, a file which 
changes size can't be backed up properly, at best you get some truncated 
initial part, at worst you get an invalid ISO filesystem. I would be 
tempted to patch the mkisofs to warn instead of stop, at least 
optionally, but I doubt that Jörg will make that part of the official 
version. The patch is reasonable easy to do, or so it seems.
