Safe NTFS write is a recent occurrence in Linux with FUSE/NTFS-3G, which went 1.0 relatively recently. It is available in the VL 5.8 series but the vasm mount scripts have not been updated yet to reflect this, because resources have been concentrated on development of a totally new vasm.
At this time, I don't think read/write to NTFS should be the default. I don't think ntfs-3g comes with any guarantees, though lots of experience shows it is safe. Nevertheless, a user should know that until recently, writing to ntfs was risky. The user should decide whether he or she is comfortable with writing to ntfs now.
What we need is some obvious instructions on how to enable ntfs-3g in /etc/fstab. Perhaps a commented line?
