I do not really know how the /pool directories of a DVD set
are supposed to be related.
When testing my proposal i did not have a full set at hand
but rather used

  for i in debian*8.1*amd*iso

which matched two ISOs in my collection of bootables:
  debian-8.1.0-amd64-netinst.iso
  debian-live-8.1.0-amd64-kde-desktop.iso

Expectably they have many /pool files in common.

If one wants to prevent overwriting but wants the xorriso
run to go on after a prevented overwrite attempt, one may
raise the abort threshold from default severity "FAILURE"
to "FATAL":

  xorriso -abort_on FATAL \
          -osirrox on:auto_chmod_on -overwrite off \
          ...

This will still emit error messages like
  xorriso : FAILURE : While restoring '/u/test/poolA/main/x/xfsprogs/xfsprogs-udeb_3.2.1_amd64.udeb' : file object exists and may not be overwritten
but courageously try to extract all other files.


The man page is huge, i confess. Everybody is invited to
ask for advise, e.g. at bug-xorriso@gnu.org .

People who use xorriso should put their favorite runs with
some comments to public places where googlers can find them.
It would be helpful to mention a few keywords which come to
the mind of the xorriso user when thinking about her/his own
use cases. (Send negative comments to upstream first ! :))


Have a nice day :)
