It seems to be not a bug, according to the answers to that question linked in the previous post.
The iso file is not mounted read only - even if the iso image file may be read only. That allows for changes in the metadata of the iso file - even if the files in the iso filesystem can not be changed. Adding the mount option "ro" to explicitly mount read only prevents the changes of the iso or udf image file, solving the problem: sudo mount -o ro,loop testimage.iso /mnt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1277146 Title: mount -o loop.... changes the udf image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kernel-package/+bug/1277146/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
