  18           acpid listens to ACPI events coming either in textual form from
  19           /proc/acpi/event (though it is marked deprecated it is still widely
  20           used and _is_ a standard) or in binary form from specified evdevs
  21           (just use /dev/input/event*).
  22
  23           It parses the event to retrieve ACTION and a possible PARAMETER.
  24           It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
  25           (if the resulting path is a directory) or directly as an executable.

  49           dmesg is used to examine or control the kernel ring buffer. When the
  50           Linux kernel prints messages to the system log, they are stored in
  51           the kernel ring buffer. You can use dmesg to print the kernel's ring
  52           buffer, clear the kernel ring buffer, change the size of the kernel
  53           ring buffer, and change the priority level at which kernel messages
  54           are also logged to the system console. Enable this option if you

 111           removable media drives. It is used to make Linux believe that a
 112           hardware disk-change switch has been actuated, which causes Linux to
 113           forget anything it has cached from the previous media. If you have
 114           such a slightly-broken drive, you will need to run fdflush every time

 683           The mount command will detect you are trying to mount a file instead

 711           Historically, Unix systems kept track of the currently mounted
 712           partitions in the file "/etc/mtab". These days, the kernel exports
 713           the list of currently mounted partitions in "/proc/mounts", rendering
 714           the old mtab file obsolete. (In modern systems, /etc/mtab should be
 715           a symlink to /proc/mounts.)
 716
 717           The only reason to have mount maintain an /etc/mtab file itself is if
 718           your stripped-down embedded system does not have a /proc directory.
 719           If you must use this, keep in mind it's inherently brittle (for
 720           example a mount under chroot won't update it), can't handle modern
 721           features like separate per-process filesystem namespaces, requires
 722           that your /etc directory be writable, tends to get easily confused
 723           by --bind or --move mounts, won't update if you rename a directory
 724           that contains a mount point, and so on. (In brief: avoid.)
 725
 726           About the only reason to use this is if you've removed /proc from
