[aklug] Re: POSIX ACLs: Mask

Answer my own question: I found the mask entry is pretty handy when you
want to quickly limit all the other ACL entries based on the file type.
E.g., maybe by default you give 10 different groups rwx permissions, but
the file is only a document, so you'll disable the x permission in the mask.
