Hi Michael,

Very nice wrap-up.  Thank you!

On a second thought, this is not optimal.  We'd better do

  sysvinit-core -> initscripts -> sysv-rc/openrc

FYI, I am planning to introduce openrc-native initscripts packaged as
"openrc-initscripts" as an alternative to initscripts.  Also in bug
827733, we will have busybox-init in the future. All the following
systems are valid to boot:

  sysvinit-core | busybox-init -> initscripts -> sysv-rc | file-rc | openrc
  sysvinit-core | busybox-init -> openrc-initscripts -> openrc

Done in openrc package git repo.

Done in systemd package git repo.

Yes, but c2 should happen first.

Done in openrc package git repo.

Yes, we are reaching consensus here.

Yeah!

I prefer the former.

Cool.  I can sense an ultimate resolution around the corner.
