[Xymon] *nix xymon client directories size (DU change is possible?)

In the client configuration, you can set the "DU" environment variable 
to the command you want to run. The Xymon client will pick up this 
setting and use it instead of the default "du -k".

Well, if you can script some way of detecting which command to use for 
which structure, that script can then be used for the "DU" env. setting.
