A device manager is a program that manages device files in the /dev directory. Permissions and changes in /dev are handled by it.
Alpine linux has several device managers available:
- mdev (from busybox) is the default.
- mdevd is standalone, compatible with mdev, more efficient.
- eudev is a complex, full-featured one.
Not available is udev since it depends on systemd which is not available on alpine. Use eudev instead.
Do I need a device manager?
Yes! Even for very specific use cases you would most likely just create a custom device manager.
