For CreationDate/ModDate, I think it should honor SOURCE_DATE_EPOCH as
in
<https://anonscm.debian.org/git/printing/ghostscript.git/tree/debian/patche=
s/2010_add_build_timestamp_setting.patch?id=3De2bf3ad7026afe13636d4937430c3=
fdae7854078>.

For the two UUIDs (and =E2=80=9CID=E2=80=9D too?), maybe we can use, say,
GS_GENERATE_UUIDS; if set to 0 or =E2=80=9Cno=E2=80=9D it=E2=80=99s disable=
, otherwise it=E2=80=99s
enabled.

Eventually we can add it to gnu-build-system.scm, but for now, given
that core-updates is well built, we should add it on a case-by-case
basis.  I don=E2=80=99t think there are that many packages that produce PDF=
s,
but I could be wrong.

How does that sound?

Thank you,
Ludo=E2=80=99.
