how come "df" can't handle the initrd root filesystem?

  from my embedded system:

# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/root                 6043      5141       595  90% /
tmpfs                    14632       636     13996   4% /tmp
/dev/mtdblock/4          29184      1428     27756   5% /jffs2

# df /tmp
Filesystem           1k-blocks      Used Available Use% Mounted on
tmpfs                    14632       636     13996   4% /tmp

# df /jffs2
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/mtdblock/4          29184      1428     27756   5% /jffs2

# df /
Filesystem           1k-blocks      Used Available Use% Mounted on
#

  so why can't i get a single-line output for the df output for "/"
when it's clearly printed in the overall output for "df"?  thoughts?
