Experiment. I create a bogus rc symlink for resolvconf. ln -s ../init.d/resolvconf /etc/rc2.d/S01resolvconf
Then I run update-rc.d with an unrelated initscript. update-rc.d alsa-utils defaults After this, the resolvconf symlink in rc2.d is still present but has been renumbered to S11resolvconf! Bad. I have added code to the postinst to do "update-rc.d resolvconf remove" if there are any S links for resolvconf in rc[1-5]. -- Thomas
