Re: [PATCH] nfs-utils: mount: really return from errno test

[Steve Dickson]

Looking further into this issue, I noticed all the following 
mounts were successful.

# mount -o v3 localhost:/home /mnt/home
# mount -o v4 localhost:/home /mnt/home
# mount -o v4 [fec0::2:5652:ff:fe20:8459]:/home /mnt/home
# mount -o v3 [fec0::2:5652:ff:fe20:8459]:/home /mnt/home

which the mount point, /mnt/home is mounted 4 different times 
to the same server. 

Is by design or a real problem?
