This includes that exit code must by default be 0. Non-zero exit values should be emitted
strictly only when the script fails. If not so, then for example installing and directy after
that removing the package would fail as the package manager things a non-zero exit code
from 'service stop' means it failed to stop.

Fixed init.d script issues
- The provided facilities should match the name of the init script.
- The given init script seems to refer to /var, possibly using a file from there.
  Without a dependency on $local_fs in Required-Start or Required-Stop, as appropriate,
  the init script might be run before /var is mounted or after it's unmounted.
- The given /etc/init.d script indicates it should be started at one of the
  runlevels 2-5 but not at all of them. This is a mistake. The system administrators
  should be given the opportunity to customize the runlevels at their will.
