[Bug 2100783] Re: systemd-boot does not support an externally provided initrd on UKI

[Nick Rosbrook]

I agree with upstream's opinion, and do not think we should ship this
patch in Ubuntu.

I understand the desire to make use of some of systemd-stub's features
without changing to a full UKI model, that is systemd-stub's primary use
case, and this patch circumvents that.

Title:
  systemd-boot does not support an externally provided initrd  on UKI

Status in systemd package in Ubuntu:
  Won't Fix

Bug description:
  We would like to boot arm and riscv using systemd-ukify, but the EFI
  stub in systemd-boot that is used by systemd-ukify to make the UKI
  only supports embedded initrd's. We would like to be able to
  externally provide the initrd. This is important for secure boot, as
  this way on kernel updates the UKI can be signed and provided as a
  package while the initrd can be generated by update-initramfs locally,
  as there are still many things changing initramfs-hooks locally.

  The patch was rejected upstream:
