It gets worse if you implement FreeBSD flavor in userland, because you
have to insert the namespace into the attribute name in order to keep
the information when using system calls.

glusterfs only uses trusted namespace, for instance.

I think the API is ill-designed too. Even the function names are at odds
with usual Unix practice.

What we can do is to depreciate the FreeBSD API, and change our code
in-tree to use the Linux API. I think moving things to userland will do
more harm than good.
