The problem is in the ISO9660 file system specifications. There is a
file size limit of 2GB. There is supposed to be a way to split up a
file into multiple extents, each not exceeding the 2 GB limit, but I
do not know how to do it with mkisofs.
The 2GB limitation does not exist for udf format. However,
$ mkisofs -udf -V "ISOS 22" -o ~/Desktop/isos22.iso .
INFO: ISO-8859-1 character encoding detected by locale settings.
Assuming ISO-8859-1 encoded filenames on source filesystem,
use -input-charset to override.
mkisofs: Value too large for defined data type. File ./myisofile.iso
is too large - ignoring
