[Xymon] df -h

[Scott Pfister]

The xymonclient-darwin.sh the xymonclient-freebsd.sh makes use of df -H out
of the box. The disk graph is based on capacity %used.  df -k or df-H
display the % used. so changing from one to the other should not impact the
graphs.  We tried this on another host and df -k or df -h displays the
columns differently and I recall having to change the [df] sed stanza to
make it display correctly.  I  don't recall the exact steps and we never
went further than the one test host. .
