| 2 | udev - a userspace implementation of devfs | |
| 3 | ||
| 4 | For more information on the design, and structure of this project, see the | |
| 5 | files in the docs/ directory. | |
| 6 | ||
| 7 | To use: | |
| 8 | ||
| bf3ca56f | 9 | - You must be running a 2.6 version of the Linux kernel. |

| bf3ca56f GKH |
11 | - Make sure sysfs is mounted. udev will figure out where sysfs is mounted, but |
| 12 | the traditional place for it is at /sys. You can mount it by hand by running: | |
| 13 | mount -t sysfs none /sys | |
| d2ce1817 | 14 | |
| bf3ca56f GKH |
15 | - Make sure you have the latest version of the linux-hotplug scripts. They are |
| 16 | available at linux-hotplug.sf.net or from your local kernel.org mirror at: | |
| 17 | kernel.org/pub/linux/utils/kernel/hotplug/ | |
| 18 | They are required in order for udev to work properly. | |
| d2ce1817 | 19 | |
| bf3ca56f GKH |
20 | If for some reason you do not install the hotplug scripts, you must tell the |
| 21 | kernel to point the hotplug binary at wherever you install udev at. This can | |
| 22 | be done by: | |
| 23 | echo "/sbin/udev" > /proc/sys/kernel/hotplug | |
| d2ce1817 | 24 | |
| bf3ca56f GKH |
25 | - Build the project: |
| 26 | make | |
| d2ce1817 | 27 | |
| bf3ca56f GKH |
28 | - Install the project: |
| 29 | make install | |
| d2ce1817 | 30 | |
| bf3ca56f GKH |
31 | This will put the udev binary in /sbin, create the /udev and /etc/udev |
| 32 | directories, and place the udev configuration files in /etc/udev. You | |
| 33 | will probably want to edit the namedev.* files to create custom naming | |
| 34 | rules. More info on how the config files are set up are contained in | |
| 35 | comments in the files, and is located in the documentation. | |
| 36 | ||
| 37 | - Add and remove devices from the system and marvel as nodes are created | |
| 38 | and removed in /udev/ based on the device types. | |
| 39 | ||
| 40 | - If you later get sick of it, uninstall it: | |
| 41 | make uninstall | |
| 42 | ||
| 43 | ||
| 44 | Things are still quite rough, and it's a bit beyond proof of concept | |
| 45 | code. Help is very much appreciated, see the TODO file for a list of | |
| d2ce1817 GKH |
46 | things left to be done. |
| 47 | ||
| a34ea8f5 | 48 | If you want to build using klibc, use the Makefile.klibc file: |
| e1b57940 | 49 | - read the klibc/klibc/README file for how to set up the linux |
| 0fba2122 GKH |
50 | symlink properly. |
| 51 | - make clean | |
| 52 | - make -f Makefile.klibc | |
| a34ea8f5 GKH |
53 | and marvel at the tiny binary you just created :) |
