Notable changes:

* The sysklogd -Z option has been removed in favor of -t option
  which has been added by upstream.
* Our own nologin.c applet has been replaced by an upstream
  nologin shell applet.

+Subject: [PATCH] nologin: Install applet to /sbin instead of /usr/sbin
+
+This is required to retain compatibility with our old custom nologin
+applet written in C which was also installed to /sbin.
+
+Compatibility with the old path is required because login shell paths
+are hardcoded in /etc/passwd.
