From 6bd12be3fa7761f190e17efdbdbff4440da7528b Mon Sep 17 00:00:00 2001 From: Chengen Du Date: Mon, 12 Aug 2024 11:41:52 +0800 Subject: [PATCH] udev: Handle PTP device symlink properly on udev action 'change' PTP device symlink creation rules are currently executed only when the udev action is 'add'. If a user reloads the rules and runs the udevadm trigger command to reapply changes, the symlink may be deleted, which can prevent the chronyd service from restarting properly.
