As I don't have enough context knowledge I hereby have the following
questions:
1. is it true that Patrick Ohly added --root/--old-root options to
mkisofs? Is this modification done to mkisofs official source or
on the Debian package? Which version since mkisofs release
software with the two options enabled?
2. And is it true Jörg is looking for people who test the version
of mkisofs with the two new options? If I am using stable
Debian, should I upgrade to unstable to be able to test Jörg's
latest version of mkisofs which has the new feature (of removing
and modifying previous session) implemented?
3. growisofs already have these features? If I move to backup with
DVD, do I must use growisofs, or simply keep on using mkisofs is
enough?
Thank you!
