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. |
