  12           dmesg is used to examine or control the kernel ring buffer. When the
  13           Linux kernel prints messages to the system log, they are stored in
  14           the kernel ring buffer. You can use dmesg to print the kernel's ring
  15           buffer, clear the kernel ring buffer, change the size of the kernel
  16           ring buffer, and change the priority level at which kernel messages
  17           are also logged to the system console. Enable this option if you

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

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

 768
 769           Booting with initramfs extracts a gzipped cpio archive into rootfs
 770           (which is a variant of ramfs/tmpfs). Because rootfs can't be moved

 772           switch_root deletes everything out of rootfs (including itself),

 806           The mount command will detect you are trying to mount a file instead
 807           of a block device, and transparently associate the file with a

 812           with loop devices) if you need to do something advanced, such as
 813           specify an offset or cryptographic options to the loopback device.

 822           Historically, Unix systems kept track of the currently mounted
 823           partitions in the file "/etc/mtab". These days, the kernel exports
 824           the list of currently mounted partitions in "/proc/mounts", rendering
 825           the old mtab file obsolete. (In modern systems, /etc/mtab should be
 826           a symlink to /proc/mounts.)
 827
 828           The only reason to have mount maintain an /etc/mtab file itself is if
 829           your stripped-down embedded system does not have a /proc directory.
 830           If you must use this, keep in mind it's inherently brittle (for
 831           example a mount under chroot won't update it), can't handle modern
 832           features like separate per-process filesystem namespaces, requires
 833           that your /etc directory be writeable, tends to get easily confused
 834           by --bind or --move mounts, won't update if you rename a directory
 835           that contains a mount point, and so on. (In brief: avoid.)
 836
 837           About the only reason to use this is if you've removed /proc from
 838           your kernel.
