From ff33b576767d5e020c9f2685a0f5b0acb35a781c Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Fri, 27 Sep 2013 20:10:38 +0200 Subject: [PATCH] dracut: Do not create early_cpio if no suitable microcode exist in hostonly case Intel microcodes only exist for very specific family/model/stepping CPUs. If no microcode gets added, there is no need to create an empty (only directories) cpio later that gets glued to the initrd. This also fixes: *** Constructing GenuineIntel.bin **** cat: /lib/firmware/intel-ucode/06-3c-03: No such file or directory in hostonly mode if there is no suitable microcode for the CPU.
