  # Shippable Fedora 24 image provides chkconfig-1.7-2.fc24.x86_64 but not the
  # latest available version (chkconfig-1.8-1.fc24.x86_64). update-alternatives
  # in chkconfig-1.7-2 fails when /etc/alternatives/dummy link is missing,
  # error is: 'failed to read link /usr/bin/dummy: No such file or directory'.
  # Moreover Fedora 24 is no longer maintained.

  # *Disable tests on Arch Linux*
  # TODO: figure out whether there is an alternatives tool for Arch Linux

  # *Disable tests on Alpine*
