UNIX System V Release 4

The SunOS 5.7 system is the Sun version of AT&T's System V Release 4 (SVR4). The system administration model is different from those in previous SunOS releases, which were more like 4.3 BSD. Differences important to device driver writers are:

• Halting and booting the machine (see the Solaris Transition Guide).

• Kernel configuration (see Chapter 5, Autoconfiguration).

• Software packaging (see the Application Packaging Developer's Guide).

For general SVR4 system administration information, see the Solaris Transition Guide.
