1/ it's an optional feature *for now*. I'd really love to see it being mandated asap. 2/ it can break the build: I don't know if this is already present in some package out there, but just think of calling a tool 'foo' setting a cli flag 'bar' to SDE: foo --bar="$(SOURCE_DATE_EPOCH)" for example, using tar: tar --mtime="@$(SOURCE_DATE_EPOCH)" -c -f out.tar in this is a valid command when SDE is set, but it's going to fail as soon as it's not set anymore, I fear; and it makes a lot of sense in a d/rules to tar something up. -- regards, Mattia Rizzolo GPG Key: 66AE 2B4A FCCF 3F52 DA18 4D18 4B04 3FCD B944 4540 .''`. more about me: https://mapreri.org : :' : Launchpad user: https://launchpad.net/~mapreri `. `'` Debian QA page: https://qa.debian.org/developer.php?login=mattia `-
