+ * specific for the minor node number).  The last field to hit will
+ * effectively be used.
+ *
+ * ALL in the minor node field marks all minor nodes to use that field.
+ * ALL in the major node field marks the end of the table.
+ *
+ * a non-NULL string in the 'dir' field allows you to prepend a

+Summary:    Fast MAKEDEV replacement
+Version:    0.2

+%description
+A replacement for MAKEDEV. Instead of parsing hard-coded text files, mkdevnodes uses the information provided in sysfs to generate device nodes with mknod() as needed, as well as a few base device nodes that always need to be present. Mkdevnodes is thus extremely fast, as it doesn not need to read and/or parse text files from the root filesystem.
