Great. Thanks!

In the long run, yes. It was a hack as a drop-in replacement of sysv-rc.

I can see sysvinit-core Depends: initscripts (>= 2.88dsf-13.3).

Hmm, I think we can express the dependency chain as

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

and drop sysvinit-core -> initscripts.

As stated above.

Good point and nice catch!

Thanks!
