Will packagers still be required to use install -p, cp -p, etc. to preserve mtimes? For some packages, the source archives mtimes will be lower than $SOURCE_DATE_EPOCH, but e.g. for ancillary Source files (e.g. systemd units) stored in distgit, using -p won't make a difference, because the mtimes aren't preserved when Koji clones the distgit repository. -- Best, Maxwell G (@gotmax23) Pronouns: He/Him/His _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
