That's all I can figure.

rtcg at host155:/etc$ /bin/df
df: cannot read table of mounted filesystems: No such file or directory

Hence the reason why I was wondering if there was another utility (or 
method) to read available disk space.

the /proc that I can see is empty.

du is to calculate the size of files - check!
'du -x' is good to keep 'du' on one file system - check!

I was just curious if there was another way to use du to calculate 
usage.  I'm probably out of luck on this issue.
