 ...
 On Linux (at least), a particular filesystem (mount point) may be
FAT,
 VFAT or NTFS (currently read-only, but read-write may eventually be
 available), 
The description of read/write NTFS in the Linux 2.2 pre-release
kernels was changed from "Experimental" to "Dangerous" a few days ago,
so I suspect it won't be any time soon.
