System Class

The system class uses a fixed-priority policy to run kernel processes such as servers and housekeeping processes like the paging daemon. The system class is reserved to the kernel. Users cannot add a process to the system class. Users cannot remove a process from the system class. Priorities for system class processes are set up in the kernel code. The priorities of system processes do not change once established. User processes that run in kernel mode are not in the system class.
