Yes.

Yes and no. Firmware can be divided in two categories:

- Those required by kernel drivers included in the installer for devices 
might be needed during the installation, mostly network or storage 
controllers. They are detected by parsing kernel messages complaining 
about missing firmware files. Obviously they must be available in the 
installer environment (initrd or installation media).

- Those known to be requested by kernel drivers not included in the 
installer for devices which are not needed during the installation such 
as graphic controllers. They are detected by matching detected device 
modalias with patterns stored in /firmware/dep11/*.patterns files 
(mostly extracted from kernel module "alias" fields at build time) for 
each firmware package.

IIUC hw-detect logic for the latter category, detected firmware packages 
are copied into a temporary cache and later installed in the target 
system. This requires firmware packages to be available at detection 
time. So I was wondering if it would be possible and desirable to 
include modalias pattern files and queue firmware packages for later 
installation from repositories like CPU microcode packages if they are 
not available in the installer environment.
