The scripts in this directory are executed each time the system enters
this runlevel.
The scripts are all symbolic links whose targets are located in
/etc/init.d/ .
To disable a service in this runlevel, rename its script in this
directory so that the new name begins with a 'K' and a two-digit
number, and run 'update-rc.d script defaults' to reorder the scripts
according to dependencies. A warning about the current runlevels
being enabled not matching the LSB header in the init.d script will be
printed. To re-enable the service, rename the script back to its
original name beginning with 'S' and run update-rc.d again.
For a more information see /etc/init.d/README.
