Upstream-Status: Backport [https://github.com/rpm-software-management/rpm/commit/a3652af66fa2a1f272d771323fee019f23d350f5] From 68a7b60f89419e53a4bd3c412f816f0576ffd8c4 Mon Sep 17 00:00:00 2001 From: Mike Crowe Date: Thu, 4 Jan 2018 14:39:51 +0000 Subject: [PATCH] Make configure cope with multiple users/groups with ID 0 If /etc/passwd contains multiple users with UID 0 then user_with_uid0 will contain a line feed which results in config.h containing: #define UID_0_USER "root (i.e. without a closing quote.) The same problem occurs with /etc/group. Let's only emit the first match in each case so that there is only ever a single result.
