    Patch add_root_cmd_groupmems.patch that we apply to shadow-native
    allows program groupmems from the shadow utility package to chroot()
    so it can be used to modify etc/passwd and etc/group if they are
    located in a sysroot.

    The --root option in groupmems is needed for class useradd.

This patch came from Slackware and address a change in crypt()'s handling
of an invalid seed, which in the past returned an encrypted string and now
returns a NULL.

The patched version of grpconv takes arguments but the check on
argc was not removed. This patch removes this check which
otherwise results in a spurious warning during rootfs creation.

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.

This fixes (or, at least, papers over) a failure in do_install for recipes which
inherit useradd.bbclass.  Rewinding optind in this way is not entirely portable
but in practice it seems to work on GNU-ish build hosts at least.
