Package: genisoimage
Version: 9:1.1.1-1
Severity: normal
Using the -stream-media-size option with genisoimage will silently break
when used with files of 4Gb or larger. The following command
illustrates this:
dd if=/dev/zero bs=1024M count=4 2>/dev/null | genisoimage\
-stream-media-size $((512*1024*4+201)) > broken.iso
The media size is specified as 2097152 sectors (4Gb) plus the 200 sectors
genisoimage needs to store metadata plus one sector (because genisoimage
seems to need more than it claims). If the ISO-9660 filesystem is then
mounted, it shows one file ("stream.img") which appears to contain zero
bytes. genisoimage does not fail, nor does it complain or warn of this
problem.
Cheers!
