2.4 Target Initialization and Administration

New support for target initialization and administration is provided in the ChorusOS 4.0 operating system:

• A new actor, ADMIN, provides administration utilities such as ifconfig, route, and netmask, which can be run before the file system is initialized.

• The C_INIT actor, loaded at system start-up, has a command interpreter which reads the sysadm.ini file embedded in the ChorusOS system image and executes any initialization instructions it finds. See the C_INIT(1M) man page for more information.

This is a more flexible and easy-to-configure approach than in ChorusOS 3.2, where network and file system initialization was handled by the IOM actor. See "System Administration in the Extended Environment" in ChorusOS 4.0 Introduction for more information.

You can customize system initialization using a /etc/rc.chorus file. See the rc.chorus(4CC) man page for more information.

To build a system image, you now need a sysadm.ini file in order to configure the network and any devices. See the sysadm.ini(4CC) man page for more information.
