I know.
The problem is that mount from util-linux has it's own
wrapper for the mount entries which is using mountinfo
while coreutils' df is just calling get_fs_usage() from
gnulib which in turn is reading /etc/mtab - which is
a symlink to /proc/self/mounts in this case.
And that file has both entries.

So the question is:
* is it a kernel thing to not expose rootfs to
  /proc/self/mounts?
* should gnulib's get_fs_usage() switch to reading
  mountinfo?
* is it a gnulib thing to not filter the rootfs
  entry?
* is it up to coreutils to filter out the rootfs
  entry?
* should coreutils' df switch to reading mountinfo?

There are several possibilities here.

Jim?
