Status of the system
_L_i_n_u_x_c_o_n_f has the unique ability to probe almost every running server
and configuration on the machine and compare them with what is
"required." Using that information, it can produce a report or take
action.
11.. PPrriinncciipplleess
_L_i_n_u_x_c_o_n_f defines the "required" configuration by looking at various
configuration files. From the content or the revision date of each
file, _L_i_n_u_x_c_o_n_f may take the following actions:
+o (Re)configure a system (change the IP number of the Ethernet
adapter)
+o Start a daemon
+o Kill a daemon
+o Kill/restart a daemon
+o Send a signal to a daemon to force it to read its configuration
file
_L_i_n_u_x_c_o_n_f can do this work in simulation mode. In this mode it simply
takes note of what has to be done. In activation mode, actions are
performed and a log entry is written in /var/adm/netconf.log.
22.. EEvveerryy ttiimmee yyoouu lleeaavvee LLiinnuuxxccoonnff
This probing is done every time you quit _L_i_n_u_x_c_o_n_f. The point is to
avoid getting into a state where a system fails to operate as expected
-- not because it is badly configured, but simply because the
configuration has not been activated.
Unfortunately, many people are convinced that rebooting is a
necessity. In fact, it is, on most other operating systems. _L_i_n_u_x and
_L_i_n_u_x_c_o_n_f are changing that idea.

The command "netconf --status" will produce a report about what has to
be done to make the system current.
The command "netconf --update" will make the system current.
If you are used to editing configuration files by hand with your
favorite editor, you can still do so. A simple "netconf --update" will
make sure everything is fine.
