The permissions seen on the mounted mountpoint are the ones from the root directory of the
mounted filesystem. They totally override the directory's permissions.
I was specifically looking for an entry I can put in the fstab because the cluster
management software I'm using has an XML definition of the filesystem where you can
specify the "options" column of the fstab entry. The entry for the mountpoint name
doesn't include the permissions.
This will have to be a post boot permission change I think.
