  [ Dimitri John Ledkov ]
  * Do not override preset defaults from auto-exported conf snippets
    loaded by initramfs-tools. This thus allows other hooks, or
    alternative confdir override the built-in defaults at mkinitramfs
    time. Specifically to support generating installer/golden/bare-metal
    initrds with all microcodes for any hardware.
