Hi,

there is a feature with cdrskin which was intended to help
its integration into cdrkit.

man cdrskin describes this option:

 fallback_program=command
        Set  a command name to be executed if cdrskin encounters a known
        cdrecord option which it does not yet support.  If  a  non-empty
        command  is  given  with  fallback_program=, and if no essential
        options are given which are specific to  cdrskin,  then  cdrskin
        will delegate the job to said command.
        The  natural  commands to be given are cdrecord or wodim but one
        may well submit the address of an own program.
        The fallback program will get all arguments of cdrskin which  do
        not  match  the  shell  patterns --?* or *_*=* . This eventually
        suppresses path names of track sources  which  happen  to  match
        those  patterns.  The  options  from  the  startup files are not
        handed to the fallback program.
        Fallback program execution is disabled if cdrskin is run  setuid
        and  not option --allow_setuid is given. In general, the drive's
        device files and the involved programs should be set up so  that
        each program runs under its advised conditions. (E.g. cdrskin as
        member of group floppy, cdrecord setuid root.)
        Two alias names for cdrskin are predefined with default fallback
        programs:
        unicord implies fallback_program=cdrecord
        codim implies fallback_program=wodim

This would make available the advantages of cdrskin with DVD
and Blu-ray media, while also offering the special CD capabilities
of wodim.

This feature was implemented in 2007. Since then it has been
fewly challenged. Thorough testing seems wise.

xorriso's mkisofs emulation has no such feature yet.


Have a nice day :)

Thomas
