Raw Blame History

From f55051678452647e035853ee94a89cb54ea2aa4a Mon Sep 17 00:00:00 2001
From: Ray Strode <rstrode@redhat.com>
Date: Fri, 17 Jul 2020 16:06:44 -0400
Subject: [PATCH] src: die during shutdown with everything else
plymouthd currently avoids getting killed at shutdown. This causes
filesystems to fail to remount read-only in some cases.
This commit changes things up so that plymouthd dies with everyone else,
but spawns a process to hold open the drm device that can keep the splash
up until the very end.
In order to keep this process alive until the very end, it gets run
from within the initramfs (if available). This requires adding service
files to jump back into the initramfs at shutdown
