  19           (if the resulting path is a directory) or directly as an executable.

  45           the kernel ring buffer. You can use dmesg to print the kernel's ring
  46           buffer, clear the kernel ring buffer, change the size of the kernel
  47           ring buffer, and change the priority level at which kernel messages

 106           hardware disk-change switch has been actuated, which causes Linux to
 107           forget anything it has cached from the previous media. If you have
 108           such a slightly-broken drive, you will need to run fdflush every time

 393           The mkswap utility is used to configure a file or disk partition as
 394           Linux swap space. This allows Linux to use the entire file or
 395           partition as if it were additional RAM, which can greatly increase
 396           the capability of low-memory machines. This additional memory is
 397           much slower than real RAM, but can be very helpful at preventing your
 398           applications being killed by the Linux out of memory (OOM) killer.
 399           Once you have created swap space using 'mkswap' you need to enable
 400           the swap space using the 'swapon' utility.

 798           The switch_root utility is used from initramfs to select a new

 801
 802           Booting with initramfs extracts a gzipped cpio archive into rootfs
 803           (which is a variant of ramfs/tmpfs). Because rootfs can't be moved
 804           or unmounted*, pivot_root will not work from initramfs. Instead,
 805           switch_root deletes everything out of rootfs (including itself),
 806           does a mount --move that overmounts rootfs with the new root, and
 807           then execs the specified init program.
 808
 809           * Because the Linux kernel uses rootfs internally as the starting
 810           and ending point for searching through the kernel's doubly linked
 811           list of active mount points. That's why.

 837           Enabling this feature allows automatic mounting of files (containing
 838           filesystem images) via the linux kernel's loopback devices.
 839           The mount command will detect you are trying to mount a file instead
 840           of a block device, and transparently associate the file with a
 841           loopback device. The umount command will also free that loopback
 842           device.
 843
 844           You can still use the 'losetup' utility (to manually associate files
 845           with loop devices) if you need to do something advanced, such as
 846           specify an offset or cryptographic options to the loopback device.
 847           (If you don't want umount to free the loop device, use "umount -D".)

 855           Historically, Unix systems kept track of the currently mounted
 856           partitions in the file "/etc/mtab". These days, the kernel exports
 857           the list of currently mounted partitions in "/proc/mounts", rendering
 858           the old mtab file obsolete. (In modern systems, /etc/mtab should be
 859           a symlink to /proc/mounts.)
 860
 861           The only reason to have mount maintain an /etc/mtab file itself is if
 862           your stripped-down embedded system does not have a /proc directory.
 863           If you must use this, keep in mind it's inherently brittle (for
 864           example a mount under chroot won't update it), can't handle modern
 865           features like separate per-process filesystem namespaces, requires
 866           that your /etc directory be writeable, tends to get easily confused
 867           by --bind or --move mounts, won't update if you rename a directory
 868           that contains a mount point, and so on. (In brief: avoid.)
 869
 870           About the only reason to use this is if you've removed /proc from
 871           your kernel.
