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.
