  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           forget anything it has cached from the previous media.  If you have
  76           such a slightly-broken drive, you will need to run fdflush every time

 760
 761           Booting with initramfs extracts a gzipped cpio archive into rootfs

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

 796           Enabling this feature allows automatic mounting of files (containing

 804           specify an offset or cryptographic options to the loopback device.

 813           Historically, Unix systems kept track of the currently mounted
 814           partitions in the file "/etc/mtab".  These days, the kernel exports
 815           the list of currently mounted partitions in "/proc/mounts", rendering
 816           the old mtab file obsolete.  (In modern systems, /etc/mtab should be
 817           a symlink to /proc/mounts.)
 818
 819           The only reason to have mount maintain an /etc/mtab file itself is if
 820           your stripped-down embedded system does not have a /proc directory.
 821           If you must use this, keep in mind it's inherently brittle (for
 822           example a mount under chroot won't update it), can't handle modern
 823           features like separate per-process filesystem namespaces, requires
