    The default UEFI iPXE bootfile is now `snponly.efi`. The boolean parameter
    `IronicIPXEUefiSnpOnly` was added to allow custom configuration. When set
    to `true` snponly is used, when `false` the previous default ipxe.efi is
    used. See bug:
    `1959726 <https://bugs.launchpad.net/tripleo/+bug/1959726>`_.
