I've seen a few alternate suggestions in the thread. I suppose the real
question is: what and where is the intended persistence for this choice?
A mount option gets it via fstab. How would a user be expected to set
it consistently via ioctl on each mount? Properties could work, but
there's more discussion needed there. Personally, I like the property
idea since it could conceivably be used on a per-file basis.
