OpenZFS dropped 'create -u' - not mounting newly created ZFS datasets automatically

[Harry Schmalzbauer]

Hello,

one of my deployment scripts fails since r364746 (Merge OpenZFS support 
in to HEAD).

The reason is '-u' seems to be dropped for zfs-create(8).
I couldn't find an option to create a dataset without automatically 
mounting it.

Am I the only one missing that possibility?

Thanks,
