[Phillip Susi]

12.10 has reached end of life, do you still have this issue on 13.04 or
13.10?

Title:
  mount does not display all mounted filesystems, including "/"

Status in “util-linux” package in Ubuntu:
  Incomplete

Bug description:
  "man mount" says:
  [CODE] 
  mount [-l] [-t type]
    lists all mounted filesystems (of type type). 
    The option -l adds the labels in this listing.
  [/CODE]

  Yet "mount" and "mount -l" do not show my root filesystem "/"
  Which of course is mounted.

  df, df -h, df -ah don't show it either.

  /proc/mounts does show it.
  df  will show it only if explicitly specified.
  "mount /" will also correctly state that it is already mounted.

  [/CODE]

  "/" is a btrfs filesystem on a memorystick card in a laptop card
  reader slot,  the entire raw card device, IE "/dev/sda" not a
  partition, shown by the /proc/mounts and "ls -l" output above.
