From 42cd4e3de927255874590e48aac960eaca507e77 Mon Sep 17 00:00:00 2001 From: nbd Date: Sat, 25 Oct 2014 17:23:14 +0000 Subject: [PATCH] base-files: add /etc/shadow to list of essential files to keep in sysupgrade (bug 18206) Based on bug #18206 sysupgrade can lead to loss of password information in certain situations. Most likely all users who will upgrade from versions r43017-43040, will lose their current passwords. :-( https://dev.openwrt.org/ticket/18206 Currently /etc/shadow is defined as a conffile in base-files: https://dev.openwrt.org/browser/trunk/package/base-files/Makefile#L37 But it is not defined in the default list of essential files to keep in sysupgrade: https://dev.openwrt.org/browser/trunk/package/base-files/files/lib/upgrade/keep.d/base-files-essential If exporting conffiles info fails, /etc/shadow can get lost. Shadow passwords are now the default, so saying that preserving /etc/passwd is essential while /etc/shadow is not, makes no sense. The attached patch adds /etc/shadow to the list of essential files.
