Daemons that must run without an LUID

Daemons that must run without an LUID

The sdd daemon process is used to start processes that must run without an LUID (such as cron). Processes that must have no LUID can be added to the /tcb/files/no_luid/cmdtable file. See the sd(ADM) manual page for more information.
