Yes, maybe, but tmpfs doesn't have any special semantics attached to
files.  It's supposed to store opaque data from userland.  Regardless
of code complexity, I just don't think this is a good idea.  What if
we later want to attach certain config meaning to or export statistics
via xattrs?  That would be quite unusual and require strong rationale
but at least fall in the similar usage as with the rest of the fs.

Thanks.
