Loading AIX kernel extensions on reboot
Greetings,
Does anyone know how to load AIX kernel extensions on reboot? I know that Oracle loads it's postwait kernel extension via a executable in /etc/inittab. I'm assuming this executable calls the "sysconfig" system call and loads it. What if I wrote my own? What is the proper way in AIX to load it automatically on system reboot? Should I edit the /etc/objrepos/Config_Rules file? I know that file loads the device drivers, which are kernel extensions themselves.
Any assistance would be greatly appreciated.
Thanks,
--Justin

reboot(3C) reboot(3C)
NAME
reboot - reboot system or halt processor
SYNOPSIS
#include <sys/reboot.h>
int reboot(int howto, char *bootargs);
The reboot() function reboots the system. The howto argument specifies the behavior of the system while rebooting and is a mask con-
structed by a bitwise-inclusive-OR of flags from the following list:
RB_AUTOBOOT The machine is rebooted from the root filesystem on the default boot device. This is the default behavior. See boot(1M) and
kernel(1M).
RB_HALT The processor is simply halted; no reboot takes place. This option should be used with caution.
RB_ASKNAME Interpreted by the bootstrap program and kernel, causing the user to be asked for pathnames during the bootstrap.
RB_DUMP The system is forced to panic immediately without any further processing and a crash dump is written to the dump device
(see dumpadm(1M)) before rebooting.
Any other howto argument causes the kernel file to boot.
The interpretation of the bootargs argument is platform-dependent.
Upon successful completion, reboot() never returns. Otherwise, -1 is returned and errno is set to indicate the error.
The reboot() function will fail if:
EPERM The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process.
