It's the only *known* case so far, but in theory could be others, even though it is strongly discouraged in the reproducible builds documentation. That tripped me up a bit in how to word it, which is why I changed the URL from the specification which doesn't mention FORCE_SOURCE_DATE on principle, to the documentation URL which does, out of pragmatism. Suggestions for better wording welcome! > It=E2=80=99s a bit of a bummer that we have to do that here, but as you p= oint > out, TeX Live can be used pretty much in any package and we=E2=80=99d rat= her not > track every possible issue by hand. > > I think it can go to =E2=80=98core-updates=E2=80=99. Wheee! Ok, will wait a bit for some improved wording suggestions from the community at large... live well, vagrant --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQRlgHNhO/zFx+LkXUXcUY/If5cWqgUCYqoHogAKCRDcUY/If5cW qsRgAQDwH5P7Rpbd0t3pgh2kEqaG1FjlRkym02amyn7WFHtUNAEAxPpW/0YgHTj8 KJfakvikyz1dH4bq+zUTfZM7b5MIGgs= =Qqav -----END PGP SIGNATURE----- --=-=-=--
