  To change a kernel variable under IRIX 5.x, use systune(1M). It saves
  the tuned kernel in /unix.install; if this file exists, it is moved to
  /unix on the next reboot. systune will change the parameters in the
  running kernel if it can, and tell you to reboot if it can't.

  To actually rebuild the kernel, use 'autoconfig -f'. This leaves the
  rebuilt kernel in /unix.install. You must reboot to begin using the
  rebuilt kernel; "rebuild your kernel" elsewhere in the FAQs implies
  rebooting.

  IRIX 4.0.x does not have systune. To change a kernel variable, edit
  the file in /usr/sysgen/master.d which contains the variable, rebuild
  the kernel and reboot.
