current Linux kernel has these features *already* in
place:

1. CONFIG_EFI_STUB
2. CONFIG_CMDLINE
3. CONFIG_INITRAMFS_SOURCE
4. Secure boot with MOK keys and .machine keyring to manage them.

Given that every single feature in IKU does exists in some form
in the Linux kernel, I think it is fair to ask why scrape away
this all existing science and reinvent the wheel?

If your reponse is "systemd", it is a tautological answerk, i.e.
same as sayig that "it is good because it is good". Not very
motivating.
