I have seen > in the past a formula K=100-S, but it obviously does not apply > universally to all daemons ( in case of AMD S=K=35). There are default values for all the services. If you just update-rc.d <service> defaults then it will install the symlinks to their default values automatically. If you have changed them, you probably need to update-rc.d [-f] <service> remove where -f forces removal. update-rc.d will notify you if you need to use it. then do the defaults update again and you should be back where you started. If you are setting up a custom configuration where services start and stop in a non-default order, then the best I can recommend is to use the ol' paper and pencil to keep notes. There may be a way to set what it considers "defaults", but I leave that to you to research. Also, if you do find a way to change the "Defaults" it may not stick around after a package upgrade. > > I can purge and re-install and the package, but I do not to loose all > configuration settings. totally unnecessary.
