This all requires that the target mode stuff is included in the initrd of course. And the system will the stay in the initrd forever.
I think that’s as minimal a boot target as you can reasonably get, or in other words you’re as far away from booting the OS as you can get.
So now the question is whether this uses any systemd-specific interfaces beyond the .service and .target files. If not, it should not take much effort to create a wrapper init script for the executable and run it on non systemd distros.
Thanks, that makes it easy to understand. Indeed, it doesn’t seem very dependent on systemd, which is great. I was aware that the project existed, and for a second thought that Poettering was trying to integrate it directly within systemd somehow whilst making improvements to it. I suppose that’s not the case, which is good.
And you’re correct, that is probably the easiest way to boot the minimum required resources.
