[Bug 1692876] Re: ubuntu-server ARM64 ISOs lack partition table with EFI System Partition

[dann frazier]

** Description changed:

  [Impact]
  On some arm64/efi platforms, the firmware will not be able to boot from an ISO dd'd to a USB stick.
  
  [Test Case]
  My test is to attach the ISO as an "HD/USB Image" to a Cavium CRB1S w/ AMI UEFI firmware using the BMC's Virtual Media. Note that the BMC requires that the file be renamed with a ".img" suffix.
  
  [Regression Risk]
- For d-i, this is aligning the xorriso boot options with the same ones now used to build the server ISO.
+ For d-i, this is aligning the xorriso boot options with the same ones now used to build the server ISO. Regression risk has been mitigated by testing on real hardware connected as both CD and disk images.
