    linter: Allow _init in modules/overrides
    
    This adds a linter rule specifically to the modules/overrides directory
    that treats the name _init as exported. That is, the linter will not
    complain if an _init is defined and not used.
    
    [skip eslint] because this doesn't just remove linter warnings, it
    changes the messages a bit. The linter job isn't smart enough to deal
    with that.
