ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
and manipulated quite freely. This capability together with our burn capability
makes possible a single binary application which covers all steps of image
composition, updating and writing. Quite unique in the Linux world.
The project components (list subject to growth, hopefully):
- libburn is the library by which preformatted data get onto optical media.
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
/dev/hdX (e.g. on kernel 2.6).
/dev/srM or /dev/hdX (e.g. on kernel 2.6).
libburn is the foundation of our cdrecord emulation. Its code is
independent of cdrecord. Its DVD capabilities are learned from
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
- libisofs is the library to pack up hard disk files and directories into a
ISO 9660 disk image. This may then be brought to media via libburn.

also allows to grow ISO-9660 filesystem images on multi-session
media as well as on overwriteable media via the same API.
