From a85c34d263fcf1542bbedcaf1634302466bb20cf Mon Sep 17 00:00:00 2001 From: Anuj Mittal Date: Wed, 19 Sep 2018 16:08:46 +0800 Subject: initramfs-framework/udev: call settle before kill When mount command is executed in rootfs module of initrd, eudev creates a loop0 device node, applies rules and adds a inotify watch to it. Right after this step, we execute finish which first tries to kill any running udevd daemon before doing a switch_root. In some cases, it is possible that switch_root is executed before inotify_add_watch was actually processed which would lead to errors like: | inotify_add_watch(6, /dev/loop0, 10) failed: No such file or directory Make sure that we process all the events in queue before actually trying to kill udevd to prevent this race.
