# Work out which firmware packages we need
|
|
# Several steps:
|
|
#
|
|
# 1. Look for packages which contain "firmware" or "microcode" in their package names
|
|
# 2. Check each of those packages to see if they contain files in /lib/firmware
|
|
# 3. For those that do, output the package name into the firmware task
