    mount_nfs.8: Note that NFSv4 requires unique /etc/hostid's
    
    Recent problems related to NFSv4 mounts has been traced
    to multiple NFSv4 clients using the same /etc/hostid
    (or kern.hostuuid, if you prefer).
    
    This patch adds a sentence to the man page noting that
    clients must have unique /etc/hostid's.
    
    This is a content change.
    
    (cherry picked from commit 603677334a6453d817df45473cedea9006b94a65)
