Entering the default state during powerup

When you power up or reboot your system, it enters the default system state that appears in the initdefault line of the /etc/inittab file. If you have installed the Network File System, (NFS(tm), this line contains a 3 in the second field, indicating that the system is to be put into networking state by default. If you do not have the NFS package installed, this line contains a 2 in the second field, indicating that the system is to be put into multiuser state by default. The following is an example initdefault entry:

   is:3:initdefault:

Once the computer boots and control passes to the unix program, the following events occur as the system enters its default state:

• Early system initializations are started by init(1M).

• root is checked and mounted by ckroot(1M).

• Filesystems are checked and mounted by bcheckrc(1M).

• The system state change is prepared by the rc2 procedure for the change to system state 2, or the rc3 procedure for the change to system state 3, depending on what your default state is.

• The system is made public using the spawning of the Service Access Facility ( ttymon(1M) and sac(1M)).

• If you have NFS installed, it is started, and remote resources are mounted and made available to you.

• The dinit script completes initialization of processes that can be delayed until after a login prompt is displayed (such as lp(1) and cron(1M)).

When all these processes have been called, the system is in the default system state (system state 2 or system state 3).
