I've got this directory /usr/local/include which has some extra ACL's
appended. Now it funnctions as I expect it would, so there's nno problem
there. 
However the Unix righs do not really make sense. Why do they have rwx for
the world whilest they do not have it? (:-)) 
Now you can do chmod 775 to the directory, but then the extended mask gets
reset to r-x. 
As a consequence the user wjw.staff.none is not allowed to create anything
in /usr/local/include.
Despite the fact that user 'wjw' is also member of the group 'local'!

wjw@eba > ls -lasg /usr/local
total 27
   1 drwxrwxrwx+  1 root     local        1024 Jan  9 13:54 .
   4 drwxrwxr-x   1 root     staff        4096 Dec 20 16:07 ..
   1 drwxrwxrwx+  1 root     local        1024 Jan  9 13:19 include

 Extended entry rights mask:      prwx-
Extended entries 
 wjw.staff.none                   prwx-

Probably are there good reasons for this, but I don't understand them.
Can anybody enlighten me?

Thanx,
