Changes: setpriv is used instead of gosu with the following flags: * Set reuid and regid to redis user and group * Clear all supplementary groups * Set bouding capabilities to an empty list * Enable no-new-privs bit * Set securebit to exclude regaining capabilities redis-sentinel is now also run with dropped privileges (previously, it wasn't) Both redis-sentinel and redis-server will start with dropped privileges, regardless of how they were started (whether using absolute paths or just file names)
redis-server may use sys_resource to increase open files limit if maxclients option has been requested
