From d6331d5583d17e4cf9f67906449cb11dcef4007c Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Sun, 18 Jun 2017 21:30:30 +0200 Subject: [PATCH] ar71xx/image: make tar calls reproducible Use --mtime when SOURCE_DATE_EPOCH is set. Use gzip -n9z instead of tar z to remove timestamp in gzip header.
