    539 This applet just calls the readahead(2) system call on each file.
    540 It is mainly useful in system startup scripts to preload files
    541 or executables before they are used. When used at the right time
    542 (in particular when a CPU bound process is running) it can
    543 significantly speed up system startup.
    544
    545 As readahead(2) blocks until each file has been read, it is best to
    546 run this applet as a background job.

    632 The watchdog utility is used with hardware or software watchdog
    633 device drivers. It opens the specified watchdog device special file
    634 and periodically writes a magic character to the device. If the
    635 watchdog applet ever fails to write the magic character within a
    636 certain amount of time, the watchdog device assumes the system has
    637 hung, and will cause the hardware to reboot.
