Preparing a spec on the subject has been on my TODO for almost two
years.  Yeah, procrastination!

For NFSv4 ACL to find their way into Ubuntu, we would need to package
nfs4-acl-tools, which can be found on the NFSv4 reference implementation
page. AFAIK, it have not been packaged for Debian yet.

There, you can also find a patch to the standard POSIX ACL tools
(set/getfacl) to do automatic translation of POSIX -> NFSv4 ACL.  Not
sure if it would worth patching our acl package with it or if we should
just stick to the implementation-specific nfs4-acl-tools.

I am fairly certain the kernel have all the right bits turned on by
default to make NFSv4 ACL happen.  That being said, I have never tried
myself, so this would need to be investigated beforehand to be
completely sure.

So far, I have not heard that many people ask for NFSv4 ACL support,
hence why I never bothered to pursue it.  But I can see it being useful
in many scenarios.
