commit efbda485ff5b3d5916971e1af656d2c21307af30
Author: Steve Dickson <steved@redhat.com>

    The wording in the exportfs man page can be a bit confusing, implying
    that "exportfs -u :/foo" will unexport /foo from all hosts, which it won't.
    
    This patch cleans that wording up and adds a couple examples on how to
    unexport directories
