[Xymon] Support for ZFS?

[Lists]

Xymon 4.3.7 doesn't seem to report on partitions created/mounted on ZFS.

Here's some sample output from df:

[root at hume db2]# df

Is there a recommended way to set up support for ZFS? I'm not looking 
for anything elaborate; simple reporting of free space as is the default 
for other FS types would be fine for my needs.
