-You can rename/relocate device nodes by using the next optional field.

+You can rename/move device nodes by using the next optional field.
+        <device regex> <uid>:<gid> <octal permissions> [=path]
 So if you want to place the device node into a subdirectory, make sure the path
 has a trailing /.  If you want to rename the device node, just place the name.

-This will relocate "hda" into the drives/ subdirectory.
-        hdb 0:3 660 >cdrom
+        hda 0:3 660 =drives/
+This will move "hda" into the drives/ subdirectory.
+        hdb 0:3 660 =cdrom
 This will rename "hdb" to "cdrom".

 If you also enable support for executing your own commands, then the file has
 the format:
-        <device regex> <uid>:<gid> <octal permissions> [<@|$|*> <command>]
+        <device regex> <uid>:<gid> <octal permissions> [=path] [@|$|*<command>]
+    or
+        <device regex> <uid>:<gid> <octal permissions> [>path] [@|$|*<command>]
 The special characters have the meaning:
         @ Run after creating the device.
         $ Run before removing the device.
