|
|
+\fBppc_rtas\fR enables userspace manipulation of the RunTime Abstraction Services (RTAS). RTAS provides for a portable method of access and setting system information. For example, you could gather information on various system sensors and set poweron values. RTAS is accessed via the /proc entry called "rtas". Manipulations on RTAS are implemented via command line arguments on /proc/rtas.
|
|
+The values for \fIuargs\fR vary greatly.
|
|
+For more information, see the \fIview/arch/ppcKconfig\fR file.

|
|
+.TP
|
|
+Invoke this helper program with the Ctrl-o key combination to save and restore the user session on the screen.

+.SH OPTIONS
|
|
+cons.saver takes only one argument, the \fITTY\fP \fINAME\fP from which the system will save and restore.
|
|
+.SH SECURITY
|
|
+Cons.saver does not need to be invoked by root. It only needs read and write access to /dev/vcsa*, which is a priviledged operation. You should create an unprivileged user, make cons.saver setuid to that user, and assure that all the vcsa* are owned by that user too.
