From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If you want to experiment with UEFI you don't need systemd-boot either, just create an efi bootable kernel and direct boot it. reFind is still around I think too for graphical boot (although that's mainly used by macs.. apple users like guis :p).
Booting the kernel directly via EFIStub from the firmware is certainly an interesting idea, although it sounds like a potential pain to manage updates. Will definitely take a look down that rabbit hole though. =)
I've been working on a tool to make management of EFI boot entries easier, specifically with the use case of booting Linux in mind.

I haven't made a public release yet though... I really should.
At this point it's pretty well battle tested.

rEFInd is finally a reasonable boot loader. It and ventoy might finally make dual boot Linux + windows viable
Isn't Ventoy used to boot images like ISOs?
