the problem is that the ACL interface changed from ufs (posix style)
to zfs (NFSv4). Bacula can handle posix style ACL, but not the new
NFSv4 ones. I have written code (for the 2.0 HEAD) which fully
supports NFSv4 ACL on Solaris 10. The problem is, the code isn't
tested well enough and I need to write regression tests for the ACL
handling.

Since we postponed the use of NFSv4 ACL in one of our projects, I
cannot do this in working hours anymore. Well, actually I ended up
programing NFSv4 ACL support in my spare time anyhow.

If there is enough interest I could port the code to the current
HEAD and start writing regression tests. A backport to 2.2.x
shouldn't be a big problem then. The drawback is that my spare time
is quite limited, so this may take a while.

Just a few further notes: Unless you are using ACL on your zfs your
data schould be save. You just have to live with the annoying error
messages. You can check for this: "find /zfs_mount_point -acl" prints
all files with ACL, "ls -V file_with_acl" show the associated ACL.
