Sort of, but not quite. OpenRC doesn't really have an rdepend on
sysvinit at all; it is the other way around. /etc/inittab is part of
sysvinit, not openrc and this is how openrc and sysvinit are used
together. It could be argued that our sysvinit package should have the
rdepend on openrc.

But, if I do that, I need to make sure that sysvinit is installed by
default, that is one reason I'm thinking about virtual/init.

A service manager is separate from the init process, so that is also why
virtual/init should be a thing. The service manager does not have to be
in the same package as the init process.
