This works fine on e.g. sparc*; I can do: shutdown -b netbsd.t -r now and it will pass "netbsd.t" as boot argument to the firmware, which passes it on to the bootloader and then it boots /netbsd.t once. No state is modified on any disks, very convenient. I don't know if there is enough of a persistent environment for UEFI boots (I would guess there is), and probably no easy way for BIOS boot.
