Learned something today. Usually if I want to make one folder look like another I create a link.
ln -s /some-folder /mnt/some-common-mount-point
The problem with this type of soft link is the system can get confused if you doing something like exporting it from NFS.
Simple solution just create a bind mount point.
mount --bind /mnt/some-common-mount-point /some-folder
or in fstab
/mnt/some-common-mount-point /some-folder bind defaults,bind 0 0
Now it will just mount the folder into the new location. It looks and acts as if you've mounted a block device.
