In SunOS 4.0 it's even documented in BOOT(8S):
boot-flags The boot program passes all boot-flags to the
kernel or standalone program. They are typi-
cally arguments to that program or, as with
those listed below, arguments to progams that it
invokes.
...
-i initname
Pass the -i initname to the kernel to tell
it to run initname as the first program
rather than the default /single/init.
Of course, you can also boot a different kernel, which lets you do even
more than run a different "init", unless you've protected the machine's
root file system so they can't install the new kernel (or have somehow
kept them from rebooting the machine or, at least, from typing a "b"
command with arguments - which would, I think, prevent either of those
from working).
