# This module handles well-known "vendor" partitions.

|

# Note that we'll be using `firmware_class.path=/vendor/firmware` on the
|
|
# command-line to make the firmware path known ASAP without requiring run-time
|
|
# configuration. The NixOS stage-2 will configure `/sys/module/firmware_class/parameters/path`
|
|
# as expected.
