[Bug 2100783] Re: systemd-boot does not support enough PE sections and externally provided initrd on UKI

[Adriano Cordova Fedeli]

** Description changed:

  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 initrd can be generated by update-initramfs while the
- UKI can be signed and provided as a package.
+ 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:
  https://github.com/systemd/systemd/pull/35978

** Summary changed:

- systemd-boot does not support enough PE sections and externally provided initrd  on UKI
+ systemd-boot does not support an externally provided initrd  on UKI
