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.
