[Nagiosplug-help] Problems with check_disk

[Ton Voon]

Jens,

I think this is a bug in check_disk. It takes the -p parameter and  
tries to find the "closest match" in the filesystems list. However,  
it should walk through the list of devices first to see if any of  
those matches exactly first.

I'll take a look at this over the next few days.
