It makes no sense for it to be unreadable.

Really if the user can files and execute chmod.

It makes no sense for it to be unreadable, and its nonreadability and
nonexecutability by `other' breaks the usability of an nfs-mounted /usr
(for the rare case that root wants to run this directly).  (If it were
only readable, then root could copy it and run the copy.)
