Next thing I will hear "Linux simple? Systemd-kernel is a lot leaner"

I think we have different definitions of lean and simple. After about a decade of Linux use I just found out Grub has modules thanks to you. You point it a disk and it installs. You edit the config file and that works. That's my experience it. I have had many debates with people who like systemd-isms , it's a fundamental difference in use case and philosophy.

Systemd-boot is not originally designed in systemd philosophy. It was originally gummiboot and got adopted into systemd project.

The explicit design goal was to be a minimal alternative to grub.
