From 91e0db96741359173ddf2be083aafcc1a3c32472 Mon Sep 17 00:00:00 2001
From: Jiaqing Zhao <jiaqing.zhao@linux.intel.com>

Subject: [PATCH] Disable shell for default users

Change the shell of all global static users other than root (which
retains /bin/sh) and sync (as /bin/sync is rather harmless) to
/sbin/nologin (as /usr/sbin/nologin does not exist in openembedded)

Upstream-Status: Backport [https://launchpad.net/ubuntu/+source/base-passwd/3.5.30]
