This can be practical to do since the automatically assigned device name may actually change around a bit due to random variation in the initialisation process of them.įor instance, eth0 can on one bootup refer to network interface A and eth1 to network interface B, but on another bootup can interface A be assigned eth1 and interface B be assigned eth0, which can cause problems if only one of them has a network cable attached and is configured to obtain an address over DHCP - the interface without the cable attached will then attempt to do that instead! If you want rename a network interface’s device name when using udev. Note: It may also be necessary to reconfigure some special packages which store device information in their configuration file, like XFree86. Now, reboot, and if you want, remove package devfsd. Remove them and create a new link to les and to les like this There are probably two links to the upper directory: les and les. Last, check the links in /etc/udev/rules.d/. Third, install the udev package, it will probably bring some dependencies too. Second, check in your /etc/fstab that you have nothing in devfs-nomenclatura, like /dev/ide/host0/bus0/target0/lun0/part3, but everything in the standard nomenclatura like /dev/hda3. So, wheter you use GRUB or LILO, remove or comment the reference to devfs=mount. Let’s see what to care about to switch from devfs to udev.įirst, the bootloader will no longer need the devfs=mount parameter on the kernel command-line. The problem is that their nomenclatura is different, so your system may be rendered unbootable. When going kernel 2.6, it may be useful to revert or upgrade to udev instead. Some of you used devfs under Woody, or under their previous Sarge install.

Upgrade from devfs to udev on Debian Sarge It replaces the hotplug package and requires a kernel not older than 2.6.12.udev – /dev/ and hotplug management daemonĪfter installing this you need to reboot your machine.

Udev is a daemon which dynamically creates and removes device nodes from /dev/, handles hotplug events and loads drivers at boot time.
