Hello.

You did a great work implementing NFSv4 ACLs into freebsd.
Only I found it difficult to add 2 acl entries for the same user or 
group, using setfacl.

I.E, if you want 2 entries for @owner :

             owner@:--x-----------:-d----:allow
             owner@:rw----a-R-c--s:fd----:allow

The only way to get this is using -a.
But -a this is pretty impractical, as you must specify a position, and 
cannot import entries from a file.

Do you know a practical way to do this easily ?
Could we modify setfacl behavior or add a -A option ?

Regards,

Arnaud Houdelette
