It seems it makes maintainers unhappy when calling `debian/rules build` and `dpkg-buildpackage` produce different results. (Note that I'm mentioning the “build” target here.) That's why I tend to think relying on something exported by `dpkg-buildpackage` is tricky. One other concern for now is that Guillem has not commented on #759999. So it's unclear to me if DEB_BUILD_TIMESTAMP is going to stay in the future. > And even if we put it in debian/rules, I think it's a good idea to > standardize on the environment name we use for this. Is there really something generic enough to be applied to all packages? For lsof (see #762433), the code already supported LSOF_CCDATE (which contained the timestamp of the build) being an empty string. So it felt proper to just modify the configure script to be able to write an empty string… For other packages, maybe upstream would rather use a date present in their changelog, or their Git repository as said earlier. For now, I don't know. Let's just fix more packages so we can figure this out. -- Lunar .''`. lu...@debian.org : :Ⓐ : # apt-get install anarchism `. `'` `-
