Seems you did get things wrong.

Mkisofs theorectically writes ISO image files up to 16 Exabytes. The size of an
ISO image is technically limited (by the ISO-9660 filesystem) to 8 Terabytes.

A 7.4 GB filesystem is more than 1000x smaller than what ISO-9660 supports.

Mkisofs supports single UDF files > 1 GB (up to 234 GB) since November 24th 2002
If you turn off consistency checks, you may write defective ISO images that
seem to include single files larger than 4 GB since then.

In a few weeks, mkisofs will support single files up to 8 TB and hide these files
(if larger tan 234 GB) from the UDF tree for consistency.

Mkisofs development is oriented on quality and reliability rather than 
implementing cheep hacks.
