hmm, you should change the initstyle from sysv
to plain too, because otherwise the 'init' task
will be the runlevel script (/etc/init.d/rc) which
will not last long enough to be noticed (as init
process ;)

well, the question here is, does this start an
init or just show you a 'fake' init ...
because the flag is really misleading and if it
wasn't for compatibility, I would have removed
it at once ...

of course, once the init process is gone, you won't
see it in any list ... even if the context remains ...
