I used to think that ISO filesystems were limited to a maximum size of 2 Gb for each file, but now I'm not sure sure. mkisofs from sysutils/mkisofs will not accept files over 2 Gb but the one in syutils/mkisofs-devel will without a problem. So if you install mkisofs-devel you can then use growisofs to make a DVD with a file over 2 Gb on it. The fun starts when you try to read the DVD! On a 4.9 machine, doing a "ls -l" shows the file size as negative, presumably just the result of using a signed 32-bit quantity to hold the size in bytes. However a 5.1 machine generates an error, something like "value too large for data type". I presume this is coming from the iso9660 filesystem layer. So there seems to be a discrepancy between what the latest mkisofs and the latest iso9660 filesystem code regards as acceptable. Which is right?
