From 6e9e19b18597103d8fe09f258cfd9904bb5f1c27 Mon Sep 17 00:00:00 2001 From: Julian Pidancet Date: Fri, 7 Oct 2011 01:13:40 +0100 Subject: Fix the --root option in shadow-native programs The add_root_cmd_options.patch that we apply to shadow-native allow the various programs from the shadow utility package to chroot() so they can be used to modify etc/passwd and etc/group if they are located in a sysroot. Some of the shadow programs (gpasswd, useradd and usermod) need to parse the command line in two passes. But we can't use getopt_long() twice because getopt_long() reorders the command line arguments, and consequently corrupts the option parsing during the second pass. This patch fixes this issue by replacing the first pass by a very simple manual walk of the command line to handle the --root argument. This change is a patch of another patch, I apologize if it is difficult to read. But IMHO it wouldn't make sense to put the patch for this issue in another separated file. The --root options in groupadd and useradd are needed to make the useradd class work, and this issue was preventing to use useradd and groupadd long options while using the class.
