  877. The only reason to have mount maintain an /etc/mtab file itself is if
  878. your stripped-down embedded system does not have a /proc directory.
  879. If you must use this, keep in mind it's inherently brittle (for
  880. example a mount under chroot won't update it), can't handle modern
  881. features like separate per-process filesystem namespaces, requires
  882. that your /etc directory be writable, tends to get easily confused
  883. by --bind or --move mounts, won't update if you rename a directory
  884. that contains a mount point, and so on. (In brief: avoid.)
  885. About the only reason to use this is if you've removed /proc from
  886. your kernel.
