Julian Pidancet - Oct. 7, 2011, 12:13 a.m.
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

Patch

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.

+2011-09-29 Fix the parsing of the --root option in gpasswd, useradd, usermod:
+
+In programs which need to scan the command line in two passes to handle 
+--root option separately from the rest of the arguments, replace the first
+calls to getopt_long with a simple iteration over the argument list since 
+getopt_long has the bad habit of reordering arguments on the command line.
