First, there's a list of known options. These are converted to a bitmask. This is then decoded and reported by mount. The other strings are passed to the filesystem directly. They decode it and do things, but they don't export them (that I can find). I believe that's why they aren't reported with 'mount'. There's a couple of other options in /etc/fstab that are pseudo options too. Warner
