Hello,

as I understand it, the sub_tree_check is only neccessary if the filesystem is 
not exported at its root. Wouldn't it make sense to let the nfs-utils 
automatically recognise that and then automatically set the option 
no_subtree_check? I mean this could be implemented easily...

Also, I would like to know what happens if one sets the 
no_subtree_check-option and re-exports the /etc/exportfs on the server or 
restarts the nfsd, but the clients still have mounted the directory?
I'm a bit scared since the man-page says that the filehandle is modified for 
this check.
Though we never had problems like Martin (at least we didn't notice), I don't 
think this check makes sense in our environment.

Thanks,
	Bernd
