From 894bcf59dc5b11ff38259a43cf4a0a3e9acada96 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Thu, 6 Dec 2018 11:09:18 +0100 Subject: [PATCH] build: Use stable file ordering in sysupgrade.tar The file ordering in the current sysupgrade depends on the order of file in a filesystem. This is often already in a sane (alphabetical order) but this is not always the case. For example, the OpenWrt build servers return a different ordering. This breaks the reproducibility of the sysupgrade tarballs significantly and also resulted in images which cannot be used for upgrades on devices like the OpenMesh A42/A62.
