mkisofs makes bad iso images after loading this week's updates

Asked by Dan Rolsma on 2011-10-29

This week's updates have broken mkisofs. Verified this on 4 different systems.

The InstallCDCustomization community documentation has a mkisofs command to create an iso image. Booting from the image it fails after answering the keyboard and language questions with "CD-ROM is not detected" (yes, same said CD I just booted off of).

I get this whether on real hardware or in VirtualBox, 32 bit and 64 bit, IDE or SATA CD-ROM. I installed a brand-spanking new Natty and Oneirc desktop, with CDs downloaded this week (alternate and desktop install), and the iso I then create has the same problem. I can still write a good iso on a Ubuntu Oneirc desktop I have not updated since I installed it Oct 18th from an iso I downloaded that same day, so something in the updates this week broke mkisofs for both Natty and Oneirc in my estimation.

Below are the commands, just an unpack and repack of the alternate iso, which boots just fine, no customizations, just to show that it is mkisofs that is the problem and not my customizations:

mkdir iso
sudo mount -o loop ubuntu-11.10-alternate-amd64.iso iso
sudo mkdir /cd-image
sudo rsync -av iso/* /cd-image
cd /cd-image
sudo mkisofs -r -V "My Install CD" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ~/my.iso .

I am posting it here for someone else to confirm before submitting it as a bug, or let me know where I am going wrong, but it works on a Oneirc desktop I have not updated since I installed it Oct 18, 2011.
