As an example. Lets say I want to test a new init-system. To do this, I
follow the (still to be written) guide on "eselect init" and boot into
new-and-shiny-init-system.
I am still used to stopping/starting services using "/etc/init.d/<service>
start/stop"
And using the "rc" command to add/remove services from the runlevel(s).
If I then, accidentally, type "/etc/init.d/xyz start" when "xyz" hasn't
been started by any means yet. What will happen?
I would assume that openrc will try to start "xyz"?
This is, I believe, something that could cause issues as dependencies
might also try to start and I then have a service running not managed by
the "new-and-shiny-init-system" that I was testing.

See above, what about if "ntpd" wasn't running yet?

See above, what about trying to start services using the method of the
not-running init?

I believe you can still use hibernate there? :)
