  794. of a block device, and transparently associate the file with a

  796. device.
  797. You can still use the 'losetup' utility (to manually associate files
  798. with loop devices) if you need to do something advanced, such as
  799. specify an offset or cryptographic options to the loopback device.

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