Subject: [PATCH] man: obey SOURCE_DATE_EPOCH when generating man pages
|
|
|
|
Previously our man pages included the current time each time they were
|
|
generated. This causes an issue for reproducible builds, since each
|
|
re-build of a package that includes the man pages will have different
|
|
times listed in the man pages.
|
|
|
|
To fix this, add support for SOURCE_DATE_EPOCH (which is a standardised
|
|
packaging environment variable, designed to be used specifically for
|
|
this purpose[1]). spf13/cobra doesn't support this natively yet (though
|
|
I will push a patch for that as well), but it's simpler to fix it
|
|
directly in docker/cli.
