[Reproducible-builds] Bug#783513: cdrkit: please allow dates in PVD to be set

[Lunar]

Package: cdrkit
Version: 9:1.1.11-3
Severity: wishlist

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that ISO images created by genisoimages could not be reproduced at a
later time. The times written the PVD are always set to the current
clock time. Same goes for RR relocations and files created on the fly
like the boot catalog.

The attached patch adds a “-creation-date” option to which can be
given an arbitrary epoch that will further be used in the PVD and for
the aforementioned files.
