used to give a user the ability to run a command as themselves
but with an expanded privilege set.
+ * Fixed a problem with the reboot and shutdown commands on some
+ systems (such as HP-UX and BSD). On these systems, reboot sends
+ all processes (except itself) SIGTERM. When sudo received
+ SIGTERM, it would relay it to the reboot process, thus killing
+ reboot before it had a chance to actually reboot the system.

* Support for using the System Security Services Daemon (SSSD) as
a source of sudoers data.
