  10. acpid listens to ACPI events coming either in textual form from
  11. /proc/acpi/event (though it is marked deprecated it is still widely
  12. used and _is_ a standard) or in binary form from specified evdevs
  13. (just use /dev/input/event*).
  14. It parses the event to retrieve ACTION and a possible PARAMETER.
  15. It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
  16. (if the resulting path is a directory) or directly as an executable.
  17. N.B. acpid relies on run-parts so have the latter installed.

  36. dmesg is used to examine or control the kernel ring buffer. When the
  37. Linux kernel prints messages to the system log, they are stored in
  38. the kernel ring buffer. You can use dmesg to print the kernel's ring
  39. buffer, clear the kernel ring buffer, change the size of the kernel
  40. ring buffer, and change the priority level at which kernel messages
  41. are also logged to the system console. Enable this option if you

  90. fdflush is only needed when changing media on slightly-broken
  91. removable media drives. It is used to make Linux believe that a
  92. hardware disk-change switch has been actuated, which causes Linux to
  93. forget anything it has cached from the previous media. If you have
  94. such a slightly-broken drive, you will need to run fdflush every time
  95. you change a disk. Most people have working hardware and can safely

  178. Linux allows you to create ramdisks. This utility allows you to
  179. delete them and completely free all memory that was used for the
  180. ramdisk. For example, if you boot Linux into a ramdisk and later
  181. pivot_root, you may want to free the memory that is allocated to the
