df: where is the root fs?

[hugo vanwoerkom <hvw59601@care2.com>]

Hi,

When I do 'df /' I get:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda6             13456580   5923184   6849832  47% /

/dev/sdc7             38456308  14630328  21872480  41% /sda7

but when I do 'tune2fs -l /dev/hda6' I get:

tune2fs 1.41.3 (12-Oct-2008)
tune2fs: No such file or directory while trying to open /dev/hda6
Couldn't find valid filesystem superblock.

Then when I do: 'fdisk -l' I get:

So here it appears that root is sda6!

What other way is there other than df to find where the root fs is mounted?
