Hi Matthias,

If  defaults  is used then update-rc.d will make links to start the service in 
runlevels 2345 and to stop the service in runlevels 016.  By default all the 
links will have sequence number 20, but this should be overridden if there are 
dependencies. For example if daemon B depends on A, then A must be started 
before B and B must be killed before A. You  accomplish  this  by  supplying  
two  NN  arguments. In general, core daemons should start early and be killed 
late, whilst applications can start late and be killed early.

In this case nvdown is not used or depending on other daemons, and it's just a 
helper script, so it's started late and stopped early.

You could go with just "defaults" if you wish.

Regards,
