Warning default start runlevel arguments do not match Default-Start values

Question

I tried to add Fuseki as a service to the correct runlevels using update-rc.d. I used sudo update-rc.d fuseki defaults and I think is okay now, but I got this warnings:

update-rc.d: warning: default start runlevel arguments (2 3 4 5) do not match fuseki Default-Start values (3 4 5)
update-rc.d: warning:
default stop runlevel arguments (0 1 6) do not match fuseki Default-Stop values (0 1 2 6)  
Adding system startup for /etc/init.d/fuseki ...
    /etc/rc0.d/K20fuseki -> ../init.d/fuseki
    /etc/rc1.d/K20fuseki -> ../init.d/fuseki
    /etc/rc6.d/K20fuseki -> ../init.d/fuseki
    /etc/rc2.d/S20fuseki -> ../init.d/fuseki
    /etc/rc3.d/S20fuseki -> ../init.d/fuseki
    /etc/rc4.d/S20fuseki -> ../init.d/fuseki
    /etc/rc5.d/S20fuseki -> ../init.d/fuseki

What exactly does this warning mean?

Answer 1

From the manual update-rc.d:

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.

It seems that, instead, the runlevels defined in /etc/init.d/fuseki are: start runlevel 3,4 and 5 as stop 0,1 and 6. This is not the default and the program alerts you that.
