Oh. Somehow i oversaw that.

That should work too, of course.

xorriso allows to define severity threshholds
for abort, for exit values with problematic
runs which did not get aborted, and for
verbosity. E.g.:

  xorriso -abort_on FAILURE \
          -return_with WARNING 32 \
          -report_about HINT \
          -as mkisofs ...

If we let the user interpret the complaints of
xorriso then we should make it rather unverbous.
Severity HINT is one notch lower than severity
WARNING. No NOTE or UPDATE messages will appear.

  xorriso ... -as mkisofs ...
rather than
  xorrisofs ...
has several advantages.
One can use its own richer option set before
switching to mkisofs emulation, and one can
easily use not-installed xorriso binaries, like

Have a nice day :)
