Re: Links in /etc/rc*.d should be treated as configuration files?

Looking at /var/lib/dpkg/postgresql.postinst on this machine, it has

  update-rc.d postgresql defaults >/dev/null
  invoke-rc.d --disclose-deny postgresql restart >$TMPFILE 2>&1

Yes, the update-rc.d invocation will create new links, but only if the
user has deleted *all* of the symlinks in /etc/rc?.d.  This is
documented in update-rc.d(8), and the canonical advice for having a
service around that you don't actually want to run is to leave the
stop links in /etc/rc0.d and rc6.d.  invoke-rc.d, if I understand it
correctly, should only start the service if it would normally be
started in this runlevel.

In other words, "we already do this."
