Then any boot loader will need to call something to start it.
Understand this: any Linux/Unix init system (systemd, SysV, Upstart,
OpenRC) is simply a program... that the Linux kernel itself executes.
That's the init= command line in the kernel.

The bootloader calls an operating system. The init system (if at all)
that the OS uses doesn't matter: so if you have an operating system,
any bootloader should be able to boot it (bearing things like being
able to understand the filesystem etc.)
