RHBA-2018:0042: dracut bug fix update (None)
The dracut packages contain an event-driven initial RAM file system (initramfs) generator infrastructure based on the udev device manager. The virtual file system, initramfs, is loaded together with the kernel at boot time and initializes the system, so it can read and boot from the root partition. This update fixes the following bug: * Microcode on AMD family 16h processors was not updated early in the boot process. With this bug fix, the issue is addressed. (BZ#1526943) Users of dracut are advised to upgrade to these updated packages, which fix this bug.
