eudev is a device manager that provides a drop-in replacement for systemd udev. It is therefore recommended for full blown desktop environments.
Installation
The easy way to setup eudev is through the setup script. Only advanced users are recommended to do manual installation.
Setup script
Setting up eudev as device manager on desktop systems is recommended in Alpine Linux. Without a fully functional device manager, users will not be able to connect to input devices. The alpine-conf package provides setup-devd script to easily install and setup device managers.
To set up eudev, issue the command:
# setup-devd udev
No need for further configuration steps as the above script takes care of all necessary changes.
Manual installation
You need to install eudev itself.
# apk add eudev udev-init-scripts
Proceed to Configuration step to configure eudev.
Configuration
Service management
To use eudev as device manager enable the following services.
# rc-update add udev sysinit # rc-update add udev-trigger sysinit # rc-update add udev-settle sysinit # rc-update add udev-postmount default
If you are not running in a Chroot, you will also want to start eudev.
# rc-service udev start # rc-service udev-trigger start # rc-service udev-settle start # rc-service udev-postmount start
Whenever udev rules are changed, for the changes to take immediate effect, use the command:
# udevadm control --reload-rules # udevadm trigger
A reboot is usually necessary for the rule changes to fully take effect.
Predictable network interface names
eudev can automatically assign predictable, stable network interface names for all local Ethernet, WLAN and WWAN interfaces instead of the traditional interface naming scheme ("eth0", "eth1", "wlan0", ...).
If you want predictable network interface names, install the eudev-netifnames package.
# apk add eudev-netifnames
Manual removal
If you are not running in a chroot you need to stop the service first.
# rc-service udev stop # rc-service udev-postmount stop
Then disable the services.
# rc-update delete udev sysinit # rc-update delete udev-trigger sysinit # rc-update delete udev-settle sysinit # rc-update delete udev-postmount default
You might also want to uninstall the packages since they are not used anymore.
# apk del eudev udev-init-scripts
