Not too say you're .iso images can't be >2GB/4GB, but I'm pretty sure
the ISO9660 standard is limited to a 2GB maximum file size (for files
within the .iso). You must use UDF to burn files of greater size.
mkisofs(8) seems to support this, if only in alpha/hybrid stage:
-udf Include UDF support in the generated filesystem image.
UDF sup-
port is currently in alpha status and for this reason, it
is not
possible to create UDF only images.
