Thanks for the review.

No, in [1] upstream indicates explicitly that they don't want to
implement reproducible builds.

[Message part 4 (text/plain, inline)]

Hi,

When trying to solve a reproducibility issue when generating the
PDF documentation of the txr software (see [1]), Paul Patience noticed
that ghostscript writes a creation date in the PDF even when the
GS_GENERATE_UUIDS environment variable is set to "0".

The attached patch updates 'ghostscript-no-header-creationdate.patch' to
fix this issue.

Given the amount of rebuilds caused by modifying ghostscript, this
should go to core-updates, but is core-updates in freeze state already,
or can I push this patch right now?

Note: Even with this patch, there are still some cases where PDF
generation by ghostscript is not reproducible (for reasons not related
to creation date), like groff-doc.
