You do realize that will mean backing everything up again....<br>

<br>
We run on Linux and only have NFSv4 ACL's applied. I am not sure why<br>
you need POSIX ACL's if you are running Linux. Very very few<br>
applications will actually check ACL's or even for that matter<br>
permissions. They just do an fopen call or similar and the OS either<br>
goes yeah or neah, and the app needs to do something in the case of<br>
neah.<br>

<br>
Samba works much better with NFSv4 ACL's.<br>
