VMWare fusion driver share-folder warning

[Jason-ZW]

When docker-machine using vmwarefusion driver, it can appear an error like this:

fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option

I think this error will make the command sudo /usr/local/bin/vmhgfs-fuse -o allow_other xxxx result non-zero code:

command := "[ ! -d " + shareDir + " ]&& sudo mkdir " + shareDir + "; sudo mount --bind /mnt/hgfs/" + shareDir + " " + shareDir + " || [ -f /usr/local/bin/vmhgfs-fuse ]&& sudo /usr/local/bin/vmhgfs-fuse -o allow_other .host:/" + shareName + " " + shareDir + " || sudo mount -t vmhgfs -o uid=$(id -u),gid=$(id -g) .host:/" + shareName + " " + shareDir
