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

55 dmesg is used to examine or control the kernel ring buffer. When the
56 Linux kernel prints messages to the system log, they are stored in
57 the kernel ring buffer. You can use dmesg to print the kernel's ring
58 buffer, clear the kernel ring buffer, change the size of the kernel
59 ring buffer, and change the priority level at which kernel messages
60 are also logged to the system console. Enable this option if you

128 hardware disk-change switch has been actuated, which causes Linux to
129 forget anything it has cached from the previous media. If you have

422 the capability of low-memory machines. This additional memory is
423 much slower than real RAM, but can be very helpful at preventing your

662 Enabling this feature allows automatic mounting of files (containing
663 filesystem images) via the linux kernel's loopback devices.
664 The mount command will detect you are trying to mount a file instead
665 of a block device, and transparently associate the file with a
666 loopback device. The umount command will also free that loopback
667 device.
668
669 You can still use the 'losetup' utility (to manually associate files
670 with loop devices) if you need to do something advanced, such as
671 specify an offset or cryptographic options to the loopback device.
672 (If you don't want umount to free the loop device, use "umount -D".)

679 Linux kernels >= 2.6.24 support unlimited loopback devices. They are
680 allocated for use when trying to use a loop device. The loop device
681 must however exist.

683 This feature lets mount to try to create next /dev/loopN device
684 if it does not find a free one.

692 Historically, Unix systems kept track of the currently mounted
693 partitions in the file "/etc/mtab". These days, the kernel exports
694 the list of currently mounted partitions in "/proc/mounts", rendering
695 the old mtab file obsolete. (In modern systems, /etc/mtab should be
696 a symlink to /proc/mounts.)
697
698 The only reason to have mount maintain an /etc/mtab file itself is if
699 your stripped-down embedded system does not have a /proc directory.
700 If you must use this, keep in mind it's inherently brittle (for
701 example a mount under chroot won't update it), can't handle modern
702 features like separate per-process filesystem namespaces, requires
703 that your /etc directory be writable, tends to get easily confused
704 by --bind or --move mounts, won't update if you rename a directory
705 that contains a mount point, and so on. (In brief: avoid.)
706
707 About the only reason to use this is if you've removed /proc from
708 your kernel.
