From acl(5):

CORRESPONDENCE BETWEEN ACL ENTRIES AND FILE PERMISSION BITS

     The permissions defined by ACLs are a superset of the permissions
     specified by the file permission bits.

     There is a correspondence between the file owner, group, and other
     permissions and specific ACL entries: the owner permissions 
correspond
     to the permissions of the ACL_USER_OBJ entry. If the ACL has an 
<==== yes, but ...
     ACL_MASK entry, the group permissions correspond to the permissions 
of
     the ACL_MASK entry.

From setfacl(1);

OPTIONS

-n, --no-mask
           Do not recalculate the effective rights mask. The default
           behavior of setfacl is to recalculate the ACL mask entry, 
unless
           a mask entry was explicitly given.  The mask entry is set to 
the <==== Oh, ah!
           union of all permissions of the owning group, and all named 
user
           and group entries. (These are exactly the entries affected by 
the
           mask entry).


setfacl.c:

int
recompute_mask (aclent_t *tgt, int tcnt, int got_mask, int got_def_mask)
{
...
 /* Recompute mask, if requested
     - If we got a mask in the input string, recompute only if --mask 
has been
       specified.
...
Your call, Corinna ... but reading setfacl(1)

Regards,

Henri
