3.2.3 Bootable information
--------------------------
[TODO]
- Addition of a boot image to a volume.
- In most cases, the catalog and the boot image itself is added to the
iso tree.
- Alternatively, user can select to add a hidden images, i.e., images
that don't appear in the iso tree.
- Modification of boot image attributes:
- bootable flag
- load segment
- load size
- Automatic patching of isolinux images. User needs to set whether to apply
this.
- Reading of El-Torito info from multisession images. Modification of its
attributes.
- Removing of El-Torito images
3.2.4 Other operations
