The filesystems do not support the same attributes. You can't create and preserve attributes that don't exist. When you close the session the files have to be in a consistent state on the native filesystem. Comprende?
For grins, please let me know how CHMOD and CHOWN work on NTFS or FAT volumes or try reading the material I referenced. Only FAT and CIFS transcend the issue, and they come to a stable state without the desired attributes. That is why you can mount a thumb drive across platforms. You can also 'mount' an NTFS volume under Linux, but again you can't preserves the required Linux permissions - there is no filesystem Metadata to do the task.
