Suppose I want a dir, which all files and directories created inside has the group permission of the group owner of the dir, and 770 as default permission. With posix ACL is really easy
#create a dir..
mkdir proof
#inherit group permission "video" in this example
chmod g+s proof/
chgrp video proof/
#with setfacl make the default group with rxw permissions
setfacl -d -m g:video:rwx proof
#other are not allowed
setfacl -d -m o:--- proof/
chmod o-x proof
#give the acl
setfacl -m g:video:rwx proof
Now I create a file and a dir inside the dir proof..
mkdir try1
drwxrws---+ 2 myuser video 4,0K feb 23 01:26 try1
touch file1
-rw-rw----+ 1 myuser video 0 feb 23 01:29 file1
As you can see I obtain what I want, all files in the dir inherit permissions and has the group "video" as group owner. This is possible on Linux (posix acl on ext4, btrfs, etc..) and Solaris (ufs).
Now the question..how to do this with zfs which use nfsv4 acl on Solaris? I have tried this making another dir "proof" in a zfs Solaris 11 host (of course chmod g+s was made)
chmod A=owner@:read_attributes/read_data/execute/list_directory/read_data/write_data/append_data/execute/add_file/add_subdirectory:fd:allow,group:video:read_attributes/read_data/execute/list_directory/read_data/write_data/append_data/execute/add_file/add_subdirectory:fd:allow,everyone@:read_attributes/read_data/execute/list_directory/read_data/write_data/append_data/execute/add_file/add_subdirectory:fd:deny proof
but the result is..
mkdir newdir
drwxr-sr-x+ 2 myuser video 2 23 feb 02.33 newdir

How to obtain the same of posix acl? Thanks
