From ce690659ef797bd26dc2be59167aa01744841510 Mon Sep 17 00:00:00 2001 From: Ian Reinhart Geiser Date: Sun, 3 Feb 2013 14:17:02 -0500 Subject: initramds-framework: add shutdown hook for udev In cases where other initramfs modules need to rely on udev running (ie in my case I have to load firmware on a device that is slow to start) there needs to be a way to keep it running during the lifecycle of the initramfs but still be shut down before swith_root is called. I added a module_pre_hook that will shut down udev before the finish module is called.
