+Bind the real control socket to a unique filename in
+.IR DIR .
+A symlink will be made pointing to the actual file used, named
+.IB feedfile _control
+in the same directory as
+.IR feedfile ,
+but since
+.IR feedfile 's
+path may be too long for an AF_UNIX socket path, innduct always
+creates the sockets in this dedicated directory which is expected to
+have a short path.  If
+.I DIR
+does not exist it will be created with mode 0700; if it does
+exist it must not be a symlink and must be owned by the user running
+innduct and have no access for "other".  If the control socket cannot
+be set up (for this or any other reason), a warning is logged, but
+such situations are not fatal for innduct's startup.  The default is
+.BR /tmp/innduct.control .
