List of directories containing firmware files. Such files
List of packages containing firmware files. Such files
will be loaded automatically if the kernel asks for them
(i.e., when it has detected specific hardware that requires
firmware to function). If more than one path contains a
firmware file with the same name, the first path in the list
takes precedence. Note that you must rebuild your system if
you add files to any of these directories. For quick testing,
firmware to function). If multiple packages contain firmware
files with the same name, the first package in the list takes
precedence. Note that you must rebuild your system if you add
files to any of these directories. For quick testing,
put firmware files in <filename>/root/test-firmware</filename>
and add that directory to the list. Note that you can also
add firmware packages to this list as these are directories in
the nix store.
