The update-rc.d calling of OpenRC is designed to be like this: insserv
makes new symlinks in /etc/rc?.d/, and then OpenRC interprets the
symlinks to populate the state to its own /etc/runlevels.

However, after the refactorization, OpenRC runs before insserv.  With a
refresh new installation of /initscripts/, OpenRC finds nothing in
/etc/rc?.d and it does nothing.  Only after that insserv installs
symlinks there.  At this stage, OpenRC knows nothing of /initscripts/.

But, the next time if some other daemon is installed, OpenRC is called
again by update-rc.d and it finds the left overs of /initscripts/
symlinks and synchroizes them.  Bug disappears!

That's why this bug is so hard to discover.  Many thanks to Axel!

Cheers,
Benda
