From 937a95449ecaad02386523f8fe2eeefbea6be971 Mon Sep 17 00:00:00 2001 From: "eric.le.bihan.dev@free.fr" Date: Fri, 7 Feb 2014 14:21:32 +0100 Subject: [PATCH] eudev: new package eudev is a userspace device management daemon. It is a standalone version, independent from systemd. It is a fork maintained by Gentoo. Features: - No extra configuration options are available: Gudev is build if libglib2 is selected. - No dependency on hwdata as the package uses its own hardware database (as does systemd). eudev 1.3 is in sync with systemd v207.
