It must've been installed and removed (but not purged).

The difference between removing a package and purging it is that
removing keeps configuration files around.  This is in case you decide
to reinstall the package later and don't want to configure it from
scratch, as far as I understand.  For historical reasons init.d scripts
are also considered configuration files.

The idea is that configuration files for uninstalled packages aren't
hurting anyone by just lying there.  This turned out to be false in this
particular case.
