Raw Blame History

From 623edeade94ef18f503ccac4296629b31bdd7515 Mon Sep 17 00:00:00 2001
From: Yu Watanabe <watanabe.yu+github@gmail.com>
Date: Wed, 4 Dec 2024 02:26:02 +0900
Subject: [PATCH] udev-config: introduce UdevConfig
Then, save configurations by their source: udev.conf, command line
arguments, kernel command line options, and udev control.
Preparation to support reloading udev.conf in a later commit.
(cherry picked from commit 04fa5c1580ad388af3477ecfd7d4aa7d7f5cee30)
Resolves: RHEL-75774
