Thanks for the information. Looks like the mount table contains entries for rootfs and /dev/sda3 that are identical. It seems that `df` ignores the `rootfs` entry.

Where is the `rootfs` device coming from? Is that LVM? Why does `df` ignore that device? At this point I have more questions than answers. I need to do some reading.
