      # The getusers function takes two filtering arguments: exclude_names and
      # exclude_ids, both a comma separated list of usernames and user IDs
      # respectively.

      # To get users with a uid 1000 and greater we generate a list of uids from
      # 0 to 999 and convert it into a comma separated string used to filter the
      # list of users.

      # Here we get a list of users except usernames nfsnobody and vagrant as
      # well as any users with uid 8 or 9
