To use:
-- Edit the udev.h file and replace the following variables with values
- that make sense for your system:
- #define UDEV_ROOT "/udev/"
- #define MKNOD "/bin/mknod"
- The only value most people will have to change is the UDEV_ROOT
- variable, as I doubt you really want device nodes to be created in my
- home directory :)
+- You must be running a 2.6 version of the Linux kernel.
-- Run make to build the project.
+- Make sure sysfs is mounted. udev will figure out where sysfs is mounted, but
+ the traditional place for it is at /sys. You can mount it by hand by running:
+ mount -t sysfs none /sys
-- Make sure sysfs is mounted.
+- Make sure you have the latest version of the linux-hotplug scripts. They are
+ available at linux-hotplug.sf.net or from your local kernel.org mirror at:
+ kernel.org/pub/linux/utils/kernel/hotplug/
+ They are required in order for udev to work properly.
-- Point /proc/sys/kernel/hotplug at the location of the udev binary that
- is created. Then plug some block devices in, or other types of
- devices that create dev files in sysfs. An easy way to do this,
- without any hardware is to use the scsi_debug module to create virtual
- scsi devices.
+ If for some reason you do not install the hotplug scripts, you must tell the
+ kernel to point the hotplug binary at wherever you install udev at. This can
+ be done by:
+ echo "/sbin/udev" > /proc/sys/kernel/hotplug
-- Watch as the nodes get created and removed.
+- Build the project:
+ make
+- Install the project:
+ make install
-Yes this is a really rough first cut, I know. It's mostly a proof of
-concept that this can actually work. See the TODO file for a list of
+ This will put the udev binary in /sbin, create the /udev and /etc/udev
+ directories, and place the udev configuration files in /etc/udev. You
+ will probably want to edit the namedev.* files to create custom naming
+ rules. More info on how the config files are set up are contained in
+ comments in the files, and is located in the documentation.
+
+- Add and remove devices from the system and marvel as nodes are created
+ and removed in /udev/ based on the device types.
+
+- If you later get sick of it, uninstall it:
+ make uninstall
+
+
+Things are still quite rough, and it's a bit beyond proof of concept
+code. Help is very much appreciated, see the TODO file for a list of
things left to be done.
Any comment/questions/concerns please let me know.
