initramfs-live-boot: Make sure we kill udev before switching root when live booting
When live booting, we need to make sure the running udev processes are killed to avoid unexepected behavior, we do this just before switching root, once we do, a new udev process will be spawned from init and will take care of whatever work was still missing [YOCTO #9520] (From OE-Core rev: e88d9e56952414e6214804f9b450c7106d04318d) Signed-off-by: Alejandro Hernandez <alejandro.hernandez@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
