	A device manager is a program that manages [https://en.wikipedia.org/wiki/Device_file device files] in the [https://en.wikipedia.org/wiki/Devfs /dev] directory. Permissions and changes in {{path\|/dev}} are handled by it.

	~~Alpine linux has several device managers available:~~
	* '''[[mdev]]''' (from {{pkg\|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.~~
