Startup for BSD 4.3 system managers

The following discusses AIX system startup for BSD 4.3 system managers.

On 4.3 BSD systems, the init program is the last step in the startup procedure. The main role of the init program is to create processes for each available terminal port. The available terminal ports are found by reading the /etc/ttys file.

On System V, the init program is started at system initialization. The init process starts processes according to entries in the /etc/inittab file.

AIX follows the System V initialization procedure. You can edit the /etc/inittab file by directly editing the file, using the telinit command, or by using the following commands:

Item Description
chitab(1) Changes records in the /etc/inittab file
lsitab(1) Lists records in the /etc/inittab file
mkitab(1) Makes records in the /etc/inittab file
rmitab(1) Removes records in the /etc/inittab file

Changes made to the /etc/inittab file take effect the next time the system is rebooted, or when the telinit q command is run.
