CREATING DEVICE NODES

- Users of udev should find device nodes created automatically. Two
- scripts are provided in Documentation/aoe as examples of static
- device node creation for using the aoe driver.
+ Users of udev should find the block device nodes created
+ automatically, but to create all the necessary device nodes, use the
+ udev configuration rules provided in udev.txt (in this directory).
+
+ There is a udev-install.sh script that shows how to install these
+ rules on your system.
+
+ If you are not using udev, two scripts are provided in
+ Documentation/aoe as examples of static device node creation for
+ using the aoe driver.
