[Feature Request] Please add option to add an extra initrd to efi image #52

Hi there,

I have been using your excellent tool for quite a number of years now and have recently migrated my system to a new laptop. Unfortunately, this one has a small bug in it`s ACPI implementation under Linux (because of course it does), so that I want/need to load a modified ACPI table during boot in order to fix S3sleep. I would therefore like to automagically incorporate this blob into my efi image that sbupdate compiles and signs.

I have provisionally done this by:

  1. Adding a new variable to sbupdate.conf - INITRD_EXTRA
  2. Adding that new vriable into the objcopy part of sbupdate, by simply adding it in between INITRD_PREPEND and initrd

Do you think, that you might put something like this into the official release?

Thank you for all your work creating and sharing this very helpful piece of software!

Hi,

This is already supported by the undocumented variable that you mentioned. You can just do

INITRD_PREPEND+=("extra.img")

in the configuration file.

Thank you, that was EXACTLY what I was looking for.

Maybe you could mention it in the readme? Just so people can have an easier time finding it.
