      If you plan to run the tests, you may want to increase the global timeout
      for them. The default value, 120 s, is not adapted to spinning disks
      (replace 200 with a value suitable for your machine):

      commands:

      To test the results, issue (adjust the individual test timeout to a
      value suitable for your machine. The default value of 10s is too
      short for spinning disks):

      call filter. On some architectures, such as i686 and ARM, the functions
      that tracker-miners uses are not guarded properly, and tracker-miners
      will get killed with a SIGSYS as a result.
